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