Abstract
We investigate temporal dynamics of nonreciprocal photon transmission between two optical modes in a three-mode optomechanical system, where the optical modes are simultaneously driven by two independent periodically amplitude-modulated lasers. We reveal that the nonreciprocal optical transmission oscillating with time can be achieved in the modulated three-mode optomechanical system. By elaborately tuning the strength of the modulation lasers, we can significantly improve the nonreciprocal optical transmission and shorten the convergence time to reach an asymptotic oscillating regime. In particular, the dependence of the temporal photon transmission on the phase difference between two independent amplitude-modulated lasers provides a flexible controllability of optical communication based on optomechanical systems.
