Abstract :
We propose and analyze an electro-optical modulator based on a gated graphene structure and utilizing the electrically-controlled Pauli blocking. It is demonstrated that the resonant excitation of plasma oscillations can lead to a substantial enhancement of the modulation efficiency in the terahertz range of modulation frequencies.
