FREQUENCY-TUNED FAR-INFRARED AND TERAHERTZ COHERENT SOURCE ON SEMICONDUCTOR NANOHETEROSTRUCTURE Russian patent published in 2013 - IPC H01S5/34 B82B1/00

Abstract RU 2478243 C1

FIELD: physics.

SUBSTANCE: frequency-tuned terahertz and far-infrared coherent source is based on a semiconductor nanoheterostructure and is excited by middle infrared band pulses. Between the source of exciting pulses and the semiconductor nanoheterostructure there is a filter in form of a plate with periodically alternating transparent and opaque strips to achieve spatial periodicity of polarisation, which is excited in the active region of the semiconductor nanoheterostructure.

EFFECT: high radiation power.
