Optical electronics:
Optical waves:
λ = 1 mm – 1 nm, f = 3·1011 - 3 ·1017 Hz
Photonics, integrated optics, …Photonics is the science and technology of generating, controlling, and detecting photons,
particularly in the visible light and near infra-red spectrum.
The goal of integrated optics is to develop miniaturized optical devices of high functionality
on a common substrate.

Optoelectronic semiconductor devices
Besides charges, photons are used for information transmission and processing. At
present there are many types of devices that are common to electronics and photonics.
Usually such devices are considered as optoelectronic devices.
Optoelectronic devices are most effectively used in optical communication
systems.
