Photonic Integrated Circuits applications from optical signal processing, optical communication, biophotonics, to sensing

Photonics is the analog of electronics in that it describes the technology in which photons instead of electrons are used to acquire, store, transmit, and process information. Photonics is a breakthrough technology as it uses photons (smallest unit of light) as the data carrier instead of electrons (smallest unit of electricity) used in electronic ICs. As light travels at very high speeds, photonics is widely used to transfer huge amounts of data at a very high speed.


Just as an Integrated circuit (IC) is a microelectronic device that houses multiple electric circuits on a chip, a photonic integrated circuit (PIC) or Integrated Photonic circuits (IPC) are devices that integrate multiple photonic functions on a chip.


This technology detects, generates, transports, and processes light. Photonic integrated circuits utilize photons (or particles of light) as opposed to electrons that are utilized by electronic integrated circuits. The major difference between the two is that a photonic integrated circuit provides functions for information signals imposed on optical wavelengths typically in the visible spectrum or near infrared 850 nm-1650 nm.


Photons are capable of traveling at the speed of light and moving through various materials without any loss. Integrated photonics may feature a very high-frequency range to allow high data throughput in an energy-efficient manner. A typical IPC may consist of single-photon sources, nonlinear photon processing circuits, and photon detectors all integrated onto a solid-state chip. Photonic integrated circuits (PICs) have attracted considerable attention owing to their small footprint, scalability, reduced power consumption, and enhanced processing stability.


Photonic integrated circuits are a combination of photonic sensors and other electronic components. They use photons (light) to perform various optical functions. In a photonic integrated circuit, signals are processed using a combination of visible and infrared radiation. Photonic sensors are used in PICs to convert the light into an electric signal.


The high speed and high bandwidth provided by photonic integrated circuits have been the major drivers for the global photonic integrated circuit market over recent years. Along with their high speed and bandwidth, photonic integrated circuits also consume less energy than conventional integrated circuits, making them doubly attractive to end users. In the case of photonic ICs, it is estimated that the power consumed in such critical applications could be reduced by at least 50%. The frequencies that could be covered with photons are about 1,000 to 10,000 times higher than the spectrum to be covered with microelectronics. This means that using photonic ICs, end-users can achieve much higher frequencies that are far more energy-efficient when compared to traditional ICs. This is likely to remain the major driver for the global photonic integrated circuit market.


Photonics has immense potential applications in many areas of present and future information and image processing technologies. The use of photonics for transmitting signals over optical low-loss fiber transmission lines provides an option to replace traditional coaxial cables used by telecommunication systems.


Photonics-based products are widely deployed in the field of optical fiber & optical free-space communications. The onset of 5G has put the focus on wireless and radio technology. However, photonics and fiber optics have been acting as critical support in transporting signals to and from the new generation of base stations.


Photonic Integrated Circuits (PIC) are slowly growing beyond the field of telecommunication and data communication that has pushed most technological developments over the past decades. Photonic integrated circuits have become widely popular in various applications, including nanoelectronics, LIDAR, calorimetry, and various silicon-based technologies.


The growing use of photonic integrated circuits in quantum computing is likely to be a major driver for the global photonic integrated circuit market. Quantum computing has become a must-have in various crucial applications in recent years due to its higher processing speed and ability to multi-function easily. Developments in quantum computing have also come on at a rapid rate in recent years due to the significant investment made by major tech players in quantum computing. This has increased the demand from the photonic integrated circuit market in recent years and is likely to be a major driver for the global photonic integrated circuit market.


Another emerging application for Photonic IC is Microwave photonics (MWP),  an emerging interdisciplinary area that investigates the interaction between microwave and optical waves for the generation, processing, control, distribution and measurement of microwave, millimeter-wave and THz-frequency signals.


However, the huge power consumption and complexity of the design may confine the expansion of the photonic integrated circuits market. This restraint creates a vital space for the development of new technologies, thus intensifying the competition in the PIC market.

Monolithic integration vs. Micro-optic assemblies

The technologies described before are used to fabricate complete optical devices using only a single material substrate: this is known as monolithic integration. This goes one step further than the current assembly of micro-optical components in miniature photonic systems. By integrating all devices into a single chip, complex assembly, alignment and stabilization processes are avoided, and packaging and testing are greatly simplified. Moreover, it is the only way to scale up complexity when moving over 20-30 components into a single package.


The election of the integration material will then determine the capabilities and limitations for the technology platform, making some of them more appropriate for certain applications than others. Currently, monolithic integration for SOI and InP relies on mature and well-established fabrication processes, rendering high yield manufacturing platforms for even the most demanding markets.

The major difference between the two is that a photonic integrated circuit provides functions for information signals imposed on optical wavelengths typically in the visible spectrum or near infrared 850 nm-1650 nm.

Application-Specific Photonic Integrated Circuit (ASPIC)

On a PIC, optical functional building blocks are connected together with waveguides.  An Application-Specific Photonic Integrated Circuit (ASPIC) is an optical chip designed for a very particular purpose, that allows to generate, manipulate and detect light signals by means of other light and/or electronic signals. An ASPIC may integrate several active optical devices, like lasers or photo-detectors, and passive structures like splitters, couplers, interferometers, filters, or polarization handling elements.


For example the integration of optical components and functions into a large scale PIC shows significant benefits when it is integrated into an optical communication system. It enables significant power, space and cost savings, new functionality and so new significant increasing transmission capacity of communication systems.


The unique ability to replace the traditional assembly of several discrete optical or micro-optical components by a single miniaturized chip, places ASPICs as the major driver for future optical systems and photonic enabled products. Such integration brings the following benefits:
• cost reduction, especially for large volumes (thousands to millions), due to lower packaging and testing costs,
• aggregation of functionalities, lowering design complexity and increasing scalability and yield, and
• decrease in size, volume and weight, with higher robustness and  simpler assemblies.


PICs still are several orders of magnitude more expensive than their microelectronic counterparts, which has restricted their application to a few niche markets. In microelectronics, there is a clear exponential development in the number of transistors per chip, which has been doubling every two years on average during the last four decades. This phenomenon is known as Moore’s law.  Similar development is occurring in micro photonics, albeit in an early stage.


Research is being done to overcome all these challenges enabling the integration of photonic components such as lasers, optical amplifiers modulators,MUX/DEMUX components and photodiodes on-chip would enable them to be used in optical signal processing, optical communication, biophotonics, and sensing applications.


Main Integration Technologies

Unlike electronic integration where silicon is the dominant material, system photonic integrated circuits have been fabricated from a variety of material systems, including electro-optic crystals such as lithium niobate, silica on silicon,  Silicon on insulator, various polymers and semiconductor materials which are used to make semiconductor lasers such as GaAs and InP.

Different technologies can be chosen to design and manufacture ASPICs, depending on the suitability of the base material to the application at hand. InP based PICs allow the direct integration of light sources and Silicon PICs enable co-integration of the photonics with transistor based electronics.

The most relevant technologies are:
• Silicon photonics: Silicon on Insulator(220 nm and 3 μm SOI), and Si based Silica on Silicon (SiO2, also known as PLC) and Silicon Nitride ( SiN and TriPleX).

• III-V photonics: Indium Phosphide (InP), Gallium Arsenide (GaAs) and derivatives: Using InP in PICs offers significant performance advantages over other substitutes such as silicon. Moreover, they find extensive applications in data transmission and telecommunications, since InP is the most important material for the generation of laser signals, and the conversion of those signals back to the electronic form. The growth of 3D-sensing applications across the industrial sector has further strengthened the demand for InP-based PICs in the photonic integrated circuits market.
• Lithium Niobate (LiNbO3) and other more exotic materials


Silica (silicon dioxide) based PICs have very desirable properties for passive photonic circuits such as AWGs due to their comparatively low losses and low thermal sensitivity. The arrayed waveguide grating (AWG) which are commonly used as optical (de)multiplexers in wavelength division multiplexed (WDM) fiber-optic communication systems are an example of a photonic integrated circuit which has replaced previous multiplexing schemes which utilized multiple discrete filter elements. Since separating optical modes is a need for quantum computing, this technology may be helpful to miniaturize quantum computers

The fabrication techniques are similar to those used in electronic integrated circuits in which photolithography is used to pattern wafers for etching and material deposition. Unlike electronics where the primary device is the transistor, there is no single dominant device. The range of devices required on a chip includes low loss interconnect waveguides, power splitters, optical amplifiers, optical modulators, filters, lasers and detectors. These devices require a variety of different materials and fabrication techniques making it difficult to realize all of them on a single chip.


Most PICs today are developed as an application-specific circuit (ASPIC), which is one of the reasons that the adoption of these optical chips is quite limited today, even when the technology has proven to be very useful for diverse applications, such as sensing, spectroscopy, and microwave processing, and the benefits of on-chip integration are similar as those of integrated electronics, in terms of cost, form factor, complexity, energy consumption and increased functionality.


Programmable photonic circuits

The growing maturity of integrated photonic technology makes it possible to build increasingly large and complex photonic circuits on the surface of a chip. Today, most of these circuits are designed for a specific application, but the increase in complexity has introduced a generation of photonic circuits that can be programmed using software for a wide variety of functions through a mesh of on-chip waveguides, tunable beam couplers and optical phase shifters.


Because they are generic and programmable, programmable PICs can change the way PICs are used in the development of new applications and products. This can be compared with programmable electronics: the widespread availability of programmable electronics (FPGAs, microprocessors, digital signal processors, …) makes it possible to implement new functions in a matter of days, without the need to fabricate custom silicon. prototyping and even product development, and only if it is needed for reasons of cost or performance, a dedicated
chip is designed and fabricated. Programmable PICs can do the same for photonics, opening up the manipulation of coherent light to a diverse range of applications. And only if a market value has been confirmed, a dedicated ASPIC needs to be made

Other raw materials including silicon and silicon-on-insulator are also widely used in photonic integrated circuits on account of low cost, easy availability, and simple fabrication offered by these materials.


Hybrid integration is the chief integration technique used for photonic integration. In 2019, the hybrid integration technique accounted for about 50% of the global market revenue share. Although it is expected to remain the major photonic integration technique, monolithic integration method is expected to witness maximum adoption, growing at a CAGR of 20.8% during the forecast period 2020 – 2028. The anticipated growth can be credited to its capability to integrate both medium and large sized photonic integrated circuits.


Furthermore, superior benefits offered in terms of reliability, power efficiency, and testing has convinced manufacturers across the globe to increasingly employ monolithic integration technique. Module integration is another technique employed for photonic integration. It accounted for the least revenue share in 2019. Over the forecast period 2020 – 2028, it is expected to exhibit sluggish growth. Inability to merge large number of optical functions and low fiber coupling integration offered as compared to other techniques is seen as the major roadblock in widespread use of module integration technique.

Europe’s plans for  leadership in Integrated photonics

Integrated photonics is explicitly mentioned in the European Chips Act, with access to enhanced and new advanced pilot lines for experimentation, testing, and validation of new design concepts. Europe already hosts a mix of medium and small foundries for silicon photonics (SiP) and indium phosphide (InP) photonics manufacturing.

Looking to provide Europe with a state-of-the-art infrastructure to support the development and manufacture of photonic integrated circuits (PICs), the EU is investing €15.5million in an international consortium called PIXAPP, which will be led by Ireland’s Tyndall National Institute. Packaging PICs can represent up to 80% of the cost of photonics components, so is a critical area for industry. PIXAPP is the world’s first open access PIC assembly and packaging pilot line, combining an interdisciplinary team from Europe’s leading industrial and research organisations.


The prime objective of PICs4All is to increase the impact of photonics and enable access to the advanced photonic integrated circuit (PIC) technologies for academia, research institutes, SMEs and larger companies. This will be achieved by establishing a European network of Application Support Centres (ASCs) in the field of PIC technology. The main task of the ASCs is to lower the barrier to Researchers and SMEs for applying advanced PICs, and thus to increase the awareness of the existence of the worldwide unique facility provided by JePPIX (InP and TriPleX PIC design, manufacturing, testing and packaging).

The main objectives of PICs4All are: active scouting opportunities for the use of PICs; promoting the use of the PIC platforms; strengthening Europe’s industrial lead in the business of integrated photonics; bringing together academia to explore photonics and promote its critical importance. These will be achieved by: reaching out to potential users that are not yet aware of the benefits of PIC’s; organizing PIC design courses, workshops; connecting users to optical chip designers; assisting access to Multi-Project Wafer runs for PIC fabrication; actual supporting in layout design and testing of prototype PICs. All the activities are advocated by publicity e.g. newsletters, application notes and participation in conferences and exhibitions.


H2020-funded INSPIRE project to lead a revolution in photonic integrated circuits with so-called micro-transfer printing technology and establishment of world-first fabrication platform. INSPIRE aims to sustain Europe’s industrial leadership in photonics by consolidating established fabrication approaches, such as those from the pioneering pure-play foundry and TU/e spinoff SMART Photonics and the silicon photonics pioneer imec, with the micro-transfer printing technology of X-Celeprint. This will result in a world-first fabrication platform that combines the strengths of two of the most well-known PIC manufacturing platforms. Methods will chiefly be developed for the coupling of SiN and InP processes, but could also be used for silicon-based photonics.


INSPIRE coordinator prof. Martijn Heck from Eindhoven University of Technology is excited by the possibilities that lie ahead: “By combining SMART and imec technologies, with only minor changes to the fabrication processes, we can leverage the major investments in the development of these platforms from the last decade. We can thus significantly reduce the time needed to transfer our technology out of the lab, and make a faster and telling impact in new application areas.”


With a €1.1 billion envelope, the Netherlands expects to occupy a prominent place on the European and global photonics scenes. PhotonDelta is a collaborative public-private ecosystem that was set up in 2018 to implement the Dutch National Plan for Integrated Photonics. It designs, develops, and manufactures solutions with integrated photonics technology. By 2030, PhotonDelta aims to create an ecosystem of hundreds of companies, serving customers worldwide through a planned production capacity of more than 100,000 wafers per year.


The €1.1 billion public-private investment includes €470 million of funding from the National Growth Fund (Nationaal Groeifonds). The rest is co-funded by TU/e, the University of Twente (UT), Delft University of Technology (TUD), Holst Center, TNO, imec, the Photonic Integration Technology Center (PITC), the Chip Integration Technology Center (CITC), OnePlanet, Smart Photonics, LioniX International, Effect Photonics, MantiSpectra, PhotonFirst, PHIX, and Bright Photonics.

Infinera PICs

Infinera company has pioneered the monolithic integration of hundreds of photonic functions, including lasers, modulators, waveguides and other optical components, into large-scale PICs, as well as the use of semiconductor manufacturing processes for PICs. PICs provide  significant flexibility and efficiency benefits when integrated into DWDM systems.


Meanwhile, electronic function integration has been progressing as CMOS (complementary metal-oxide semiconductor) technology continues to improve. As feature sizes have shrunk and design tools improved over the years, the maximum complexity possible in an application specific integrated circuit (ASIC) has grown from thousands of gates to several hundreds of millions. This level of integration delivers higher processing power in terms of GBaud (symbol rate) and bits per symbol, thereby allowing higher order modulation formats and coherent detection, ultimately resulting in better capacity reach performance.


Infinera combines large-scale PICs with coherent ASICs, two important technologies for 500 Gb/s and terabit super-channel transmission. In the first coherent era, Infinera’s transmitter modulators were driven directly, and the optical impairments resulting from transmission were compensated for in the receiver by Infinera’s FlexCoherent Processor. When this technology was introduced into the market, it enabled the move from 10 Gb/s to 100 Gb/s per channel, a tenfold increase in fiber capacity, and at the same time increased the typical optical reach from about 2,500 kilometers to about 4,500 kilometers.


Infinera’s latest FlexCoherent design introduces transmitter based processing and enhances receiver-based capability in which the transmitter modulators are now driven by the combination of an advanced DSP and a digital-to-analog converter (DAC), which improves spectral shaping. This new design, combining electronic and photonic enhancements, introduces new capabilities, enabling operators to improve their fiber capacity reach performance
