Abstract

Abstract: We show multiple mechanically induced switching of a weak probe field through a system of cavity-optomechanics with a medium of N number of three levels (Λ-type) atoms exhibiting a strong coherent field coupling. Three distinct MIT windows develop for the probe field transmission using optomechanical coupling together with two other coupling parameters related to the two atomic transitions. Adjustment of the relative phase associated with the coupling parameters leads to multiple absorption-induced optical switching. The switching is obtained by closing one through three of the MIT windows for the probe field transmission tuning the relative phase and vice versa. Contrary to the multiple mechanical induced transparency, the optical switching phenomenon is explained regarding constructive quantum interference effect in the system.
