Synopsis:

The subject treats the principles of operation of the optical radiation sources, optical signal amplifiers and detectors of the optical signals as well as the field of application of the devices. All kinds of injection and dielectric lasers are discussed. The amplifiers and detectors of the optical signals, photonic receivers and transmitters are studied, too. In great detail are discussed applications of the optical integrated circuits, optical communications and optical sensors.
