Optical tunable modulator based on graphene metamaterials at terahertz communication range

Optical tunable modulator based on graphene metamaterials at terahertz communication range

An optical graphene-based external modulator has been proposed. Through the destructive interference of excited optical modes, an obvious plasmon-induced transparency effect can be achievable. By adjusting the physical parameters of graphene patterned structure, we select a structural parameter with...
