Nanophotonics technology trends and market

Nanotechnology deals with the understanding, control and manufacture of matter in the nanoscale regime, usually between 1 nm to 100 nm, and exploiting them for a useful application. At this length scale unique properties and phenomena arise as a result of increased surface-to-volume ratio and dominance of quantum mechanical effects. The field has opened up opportunities to design, manipulate and control structures and devices at the nanometer scale down to the molecular and even atomic level, offering improved or new functionalities.


The domain of nanotechnology encompasses a very large area. Nanophotonics or nano-optics is the study of the behavior of light on the nanometer scale, and of the interaction of nanometer-scale objects with light.  Novel properties and phenomena occur when photons interact with nanostructures. This has led to the emergence of nanophotonics – a confluence of photonics and nanotechnology. Indeed, recent progress in nanophotonics has revealed that nanophotonic-based devices and applications can be powerful candidates for replacing the conventional bulky optical components in a compact manner.


Light is the cornerstone of our modern information society. It uniquely can transmit information at the ultimate speed of the universe. However, it is a daunting challenge to miniaturize photonic devices to the nanometer scale because of the weak coupling between light and matter.


One way to picture the interaction of light and matter in a nanophotonic material is to consider a photonic crystal. A photonic crystal is a material that has a nanostructure which affects the motion of electromagnetic energy. Photonic crystals can be used in different applications including telecommunications, security dyes and paints.




Nanophotonic engineering with carefully chosen materials and geometries can dramatically enhance the interaction of nanoscale structures with light. This revolution in optics has led to the creation of whole new types of sensors, ultrafast switches, and artificially engineered materials (metamaterials) which have properties and functionalities unattainable in naturally occurring materials.


It has recently become a broadly recognized research field, and it will play an incredible role in the advancement of groundbreaking emerging innovations, ranging from high-efficiency solar cells to customized health tracking instruments that can detect the chemical structure of molecules at ultralow concentrations.


Some nanophotonic applications involve interacting with light while others involve the emission of light. Examples of nanophotonic applications that involve the emission of light include quantum dots, OLED, sensor applications, and next generation silicon based emitting devices.


Quantum dots are luminescent materials that are currently being studied for light emitting processes. Quantum dots are typically made from inorganic materials including cadmium, indium, lead, phosphorus, selenium, and sulfur.


The study has the potential to revolutionize the telecommunications industry by providing low power, high speed, interference-free devices such as electrooptic and all-optical switches on a chip. A few examples of devices are on-chip and chip-to-chip interconnects, optical switches, optical waveguides as well as the nonlinear electro-optic devices, modulators, and waveguides.


In recent years, the introduction of ultra-thin nanomaterials such as atomic-thin transition metal halides, which are used in low-sensitivity optical sensors, may open up many new possibilities in the detection of environmental gases



The study of nanophotonics involves two broad themes 1) studying the novel properties of light at the nanometer scale 2) enabling highly power efficient devices for engineering applications.


It encompasses the investigation of novel optical interactions, materials, manufacturing techniques, and models, as well as the exploration of organic and inorganic, or chemically manufactured structures such as holey fibers, photonic crystals, sub-wavelength structures, quantum dots, and plasmonics.


Technologies in the realm of nano-optics include near-field scanning optical microscopy (NSOM), photoassisted scanning tunnelling microscopy, and surface plasmon optics. Traditional microscopy makes use of diffractive elements to focus light tightly in order to increase resolution. But because of the diffraction limit (also known as the Rayleigh Criterion), propagating light may be focused to a spot with a minimum diameter of roughly half the wavelength of the light. Thus, even with diffraction-limited confocal microscopy, the maximum resolution obtainable is on the order of a couple of hundred nanometers.


The scientific and industrial communities are becoming more interested in the characterization of materials and phenomena on the scale of a few nanometers, so alternative techniques must be utilized. Scanning Probe Microscopy (SPM) makes use of a “probe”, (usually either a tiny aperture or super-sharp tip), which either locally excites a sample or transmits local information from a sample to be collected and analyzed. The ability to fabricate devices in nanoscale that has been developed recently provided the catalyst for this area of study.


It is concerned with the use of photonics in nanostructure media, when light is compressed down through nanometer scale volume and field enhancement effects emerge, resulting in new optical wonders that can be used to counter current advanced cutoff points and produce dominant superior photonic devices, which include a wide range of topics, such as metamaterials, quantum dots, quantum nanophotonics, high resolution imaging, plasmonics, and functional photonic materials.  Surface plasmonics (collective oscillation of free electrons near the surface due to electromagnetic interaction) and meta materials are promising areas in nanophotonics.


Nanomaterials establish a substantial space in nanophotonics, and as we can see in this section and others to come, nanoscale optical materials span a wide variety of optical applications and have an incredibly diverse spectrum of nanostructure architecture. The optical properties of these nanostructures can be closely monitored by modifying them, allowing for the enhancement of one photonic function when presenting another photonic manifestation, and also the convergence of several functions to achieve multifunctionality



Nanoplasmonics structures such as nanoantennas or amplifiers significantly enhance the electric field of the incoming electromagnetic waves and coupling of incoming photons to the photovoltaic material.


Metamaterials have several unusual properties such as magnetism at optical frequencies, negative refractive index, large positive refractive index, zero reflection, perfect absorption, giant circular dichroism, enhanced nonlinear properties etc. The typical feature sizes are from 10 nm to 100 nm for optical frequencies. Theoretically, an object can be made invisible by bending the light around its surface using suitable metamaterial. The expected application domains of metamaterials are communication systems, NBC-RE sensing and detection, absorbers, acoustics, high-resolution imaging and compact optics, cloaking devices, etc. Metamaterials will allow us to tailor properties of materials or create materials with properties which are non-existing in natural materials.


Technology trends

Moving into the future, nanophotonics and metamaterials promise to play a key role across an astonishing variety of technologies. Just a few examples are: refractory plasmonics to be used in power generation, metamaterials and lenses for AR/VR, and the rapidly developing field of quantum nanophotonic devices that will power quantum communication and information processing.


One of the new trends is tunable nanophotonics using active and tunable photonic devices. Researchers have used chalcogenide phase-change materials that can be easily integrated into nanophotonic platforms and thereby provide reconfigurability of optical functionalities.


Another trend is the combination of nanophotonics with deep learning, which has seen an explosion in interest recently. Specifically, researchers are exploring the application of deep learning to inverse design in nanophotonic devices. Jiang and Fan have presented a global optimization algorithm that uses deep learning to design metasurfaces. The proposed optimization method considers populations and a generative neural network that is trained to optimize the population of the devices. The process allows efficient global optimization, which can be extended to general inverse design problems in other areas of physics.


Researchers are also exploring 3D and 4D printing for nanofabrication of active and responsive nanophotonic devices.
