摘要：

The control of slow and fast light propagation is a challenging task. Here, we theoretically study the dynamics of a driven optomechanical cavity coupled to a charged nanomechanical resonator (NR) via Coulomb interaction. 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. In comparison with previous schemes, the clear advantage of our scheme is that we can simply switch from fast-to slow-light in two signal modes by only adjusting the laser-cavity deturning from Delta = omega(1) to Delta = -omega(1). The proposal may have potential application in optical router and quantum optomechanical memory.
