Multiple optomechanically induced transparency in a ring cavity via Coulomb interaction

摘要

Abstract The absorptive property of a ring optomechanical cavity is theoretically studied by coupling a charged nanomechanical resonator via Coulomb interaction. The multiple optomechanically induced transparency windows in the output field are observed. The results show that in a ring optomechanical cavity with two movable mirrors the output field presents two transparency windows. The two transparency windows split into three transparency windows when the third movable mirror is added by Coulomb interaction in this optomechanical system. We find that the distance between transparency windows is changed, but the width of each transparency window still remains unchanged when the Coulomb interaction strength is modulated. The width of each transparency window can be widened with the increase in pump power.
