Photonics is the science of using and controlling photons, which is the smallest unit of light. Photonics allow for faster transfer of data than traditional electronic circuits. Integrated photonics allow designers and manufacturers to put thousands of photonic components (such as lasers, detectors, waveguides, modulators, electronic controls, and optical interconnects) together on a single chip, allowing capabilities that were not previously possible.
Photonics is used in a wide range of applications including: telecommunications, laser based radar, Datacom, sensing, and many others. It currently powers the Internet as we know it today. Integrated photonics provides significant reduction in size, weight, and power, and while dramatically improving performance and reliability.
