The discerning of optomechanically induced transparency and Autler-Townes splitting in an optomechanical system

Abstract

Optomechanically induced transparency (OMIT) which exhibits a transparent window in the absorption spectrum of the optical field has been observed in the optomechanical systems. Autler-Townes splitting (ATS) which describes the coherent superposition of the fields presents also a similar transmission spectrum. Here in this study, we analyze these two effects and find that the performance of OMIT and ATS could be effectively manipulated through the tuning of the coupling rate and the loss rate. We numerically compare the quantity of the two phenomena using the Akaike Information Criterion, the Bayesian Information Criterion and the Hannan-Quinn Criterion, respectively.
