Application of Graphene to Ultrahigh-Frequency Optoelectronic Devices

Abstract

  Graphene, a single-layer sheet of carbon atoms, having a unique optoelectronic property different from the conventional two-dimensional electron systems has attracted attention as a promising new optoelectronic material that can overcome the performance limitations of the prior devices. In this paper, we describe the recent advances and trends in the developments of ultra-high frequency optoelectronic and plasmonic devices focusing on the terahertz lasers using graphene-based material systems.
