Graphene Photonics, Plasmonics, and Broadband Optoelectronic Devices

TLDR

Graphene, celebrated for its electronic properties, is now a leading material in photonics because its optical characteristics enable signal emission, transmission, modulation, and detection within a single platform. This paper reviews the latest progress in graphene photonics, plasmonics, and broadband optoelectronic devices. The review focuses on integrating graphene photonics onto silicon for broadband light routing and amplification, covering components such as polarizers, modulators, photodetectors, saturable absorbers, and optical limiters.

Abstract

Graphene has been hailed as a wonderful material in electronics, and recently, it is the rising star in photonics, as well. The wonderful optical properties of graphene afford multiple functions of signal emitting, transmitting, modulating, and detection to be realized in one material. In this paper, the latest progress in graphene photonics, plasmonics, and broadband optoelectronic devices is reviewed. Particular emphasis is placed on the ability to integrate graphene photonics onto the silicon platform to afford broadband operation in light routing and amplification, which involves components like polarizer, modulator, and photodetector. Other functions like saturable absorber and optical limiter are also reviewed.
