Graphene-Based Optoelectronics

Owed to its extraordinary electronic, thermal, and optical properties, as well as its integration possibilities and low cost, graphene has emerged as an attractive material for a myriad of optoelectronic applications. Although just one atom-thick, single-layer graphene is capable of efficiently interacting with optical waves over a wide spectral range extending from terahertz to visible frequencies. Moreover, its intrinsic nature enables the integration of graphene with silicon-based photonic devices in CMOS compatible processes. This paper reviews and discusses recent progress on graphene-based optoelectronic devices for modulating, detecting, generating, and beam-shaping optical waves in a broad range of wavelengths extending from ~500 nm to ~500 μm.
