ELECTRONICALLY CONTROLLED NONLINEAR DEVICES BASED ON THE GRAPHENE PLASMONICS PLATFORM IN THE FAR AND MID-INFRARED RANGE. REVIEW

Abstract

Background. The relevance of the topic is due to the need to master the infrared (IR) range for optical telecommunication systems, IR spectroscopy and biophotonics applications and is dictated by the needs of nonlinear IR optics for the implementation of active optical functions based on graphene, such as generation of IR radiation, frequency conversion for applications in optical communications, materials processing, precision measurements, spectroscopic sensing and biological sensors. The purpose of this work is to present the principles of construction and operation of electrically tunable nonlinear devices in the far and mid-IR range: harmonic generators and multipliers, frequency converters and mixers based on graphene metasurfaces using the latest achievements of graphene plasmonics. Materials and methods. Graphene plasmonics. Results and conclusions. The unique properties make electronically controlled nonlinear devices in the far and medium IR range a promising choice for the future nonlinear frequency converter, optical control and information processing on a graphene plasmonics board.
