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). Photonics 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.


Not Really
Photonics was predicted to become mainstream by 2005, as this article from PC Magazine in 1995 forecast. Light-based computers have yet to materialize; however, today's PCs have long exceeded these storage and RAM projections.
