photonics

[fō′tän·iks]
(electronics)
The electronic technology involved with the practical generation, manipulation, analysis, transmission, and reception of electromagnetic energy in the visible, infrared, and ultraviolet portions of the light spectrum. It contributes to many fields, including astronomy, biomedicine, data communications and storage, fiber optics, imaging, optical computing, optoelectronics, sensing, and telecommunications. Also known as optoelectronics.

photonics

The science of generating and transmitting light (photons). It deals with light starting in the infrared range, through visible light to ultraviolet light at the highest frequency. Most photonic systems use electricity and electronic circuits as their source of energy. See optoelectronics, silicon photonics and spectrum.
