Silicon photonics market entering large growth driven by 5G, large data centers, real time cloud-computing, big data analytics, Exascale supercomputers , Military and Aerospace

Silicon photonics refers to the application of photonic systems using silicon as an optical medium. Silicon photonics (SiPh) is a material platform from which photonic integrated circuits (PICs) can be made. It uses silicon on insulator (SOI) wafers as the semiconductor substrate material and most of the standard CMOS manufacturing …

Photonic Integrated Circuits technologies promise Quantum computers and sensors, as system-on-chip solutions integrated into laptops and cell phones.

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 very high speeds, photonics is widely used to transfer huge amounts of data at a very high speed. Thus …

Optical Fiber Network Technologies enabling terabit per second optical fiber networks for 5G, fiber-to-the-home (FTTH)

An optical network is a communication system that uses light signals, instead of electronic ones, to send information between two or more points. The points could be computers in an office, large urban centers or even nations in the global telecommunications system. These include limited range local-area networks (LAN) or wide-area …

DARPA OpTIm developing room-temperature Quantum-Level Infrared Detectors

Electromagnetic energy, produced by the vibration of charged particles, travels in the form of waves through the atmosphere and the vacuum of space. These waves have different wavelengths (the distance from wave crest to wave crest) and frequencies, These two are inversely related to each other,  the shorter the wavelength, …
