In an optical communication link, noise attributable to the statistical nature of optical quanta. [FAA] See quantum noise.

Referring to or using opto-electronic, electro-optic, or magneto-optic phenomena.
Note: Photonic devices include a wide variety of active devices that are used in countless applications in the fields of optical detection and imaging, optical communications systems, direct optical-to-electrical power generation, etc. For example, phtonic devices include, but are not limited to: light-emitting diodes (LEDs), injection laser diodes (ILDs), avalanche photodiodes… (Read More →)

A variety of computer in which the electronic circuits (which process data serially) are replaced by faster and more powerful photonic circuits (which can perform parallel processing).

The use of photonic devices rather than electronic devices to make or break connections within integrated circuits.

The science of generating and harnessing light as well as other forms of radiant energy whose quantum unit is the photon.

Facsimile recording by the exposure of a photosensitive surface to a signal-controlled light beam or spot.

The production, as a result of the absorption of photons, of a voltage difference across a pn junction.
Note: The voltage difference is caused by the internal drift of holes and electrons.
