Optical Transistor and Coherent Optical Storage Based on Graphene Optomechanics System
Abstract: Graphene, atomically thin two-dimensional nanomaterials, may be considered as the ultimate nanomaterial for fabricating nanomechanical resonator due to its unique properties for studying its quantum behavior of the motion. In this work, we theoretically demonstrate optomechanically induced transparency based on the coupled graphene nanomechanical resonator-microwave cavity system with a strong microwave pump field and a weak signal field under the condition of red sideband. At the blue sideband, the signal field can be efficiently attenuated or amplified with calculating the transmission spectrum of the signal field, depending on the power of a second “gating” (pump) field which can behave as an optical transistor to amplify a weak microwave field. In addition, the graphene optomechanics can obtain the slow and fast light effect with controlling the strong pump field, and the slow and fast light effect can be switched via adjusting the detuning between the cavity field and the pump field. This scheme may be a promising candidate for light storage and pave the way for numerous applications in telecommunication and quantum information technologies.
