Graphene-Based Hyperbolic Metamaterial Acting as Tunable THz Power Limiter

In this paper, we investigate the possibility of employing a graphene-based hyperbolic metamaterial as tunable optical power limiter and/or controllable laser noise suppressor for terahertz frequency range. This is first time that mentioned functionalities are obtained with voltage-controlled nonlinear utilizing graphene. We believe such structures, feasible by means planar deposition techniques, will find practical applications in THz systems requiring limiting.
