Controlling optomechanically induced transparency through rotation

Abstract

In this article, we describe controlling the optomechanically induced transparency (OMIT) phenomena through rotation. An optomechanical cavity, which is coupled to a weak probe field and to a strong drive field, is placed along the diameter of a rotating table. When the table rotates, the centrifugal force due to rotation changes the length of the optomechanical cavity because of which the transparency window in OMIT disappears. We further point out that OMIT can be recovered by shifting both the drive and probe frequencies simultaneously. We derived an analytic parameter to estimate the minimum angular velocity that can effect OMIT for a given optomechanical cavity. In other words, we describe turning on and turning off OMIT by controlling the rotation rate.
