Tunable switch between slow and fast light in optomechanics with a squeezed field

Résumé fourni par la source

Abstract We study the dynamics of a driven optomechanical cavity coupled to a charged nanomechanical resonator via Coulomb interaction with a squeezed field. We find that the tunable switch between slow and fast light for two signal modes can be observed from the output field by adjusting the laser-cavity detuning in this system. Moreover, the frequencies of two signal light can be tuned by Coulomb coupling strength, which are feasible using current laboratory techniques. The proposal may have potential application in optical router and quantum optomechanical memory.
