The Study Of Optical Transmission Characteristics Based On Cavity Optomechanical Systems

Whispering gallery mode cavity photomechanical systems combines nano-mechanical vibrator and optical micro-cavity system,which can use optical radiation pressure to induce the interaction of optical mode and mechanical mode based on the action of light field.In recent years,with the increasing research on optical information processing,the exploration of quantum optical effects in cavity photomechanical systems has become particularly important.In this paper,the following works have been carried out with the main objective of investigating the presence of Electromagnetically Induced Transparency effect(EIT)and Autler-Townes splitting(ATS)in cavity optomechanical systems.??By theoretical derivation and simulation,it is concluded that both Optomechanically Induced Transparency(OMIT)and ATS exist in the cavity photomechanical system of the whispering gallery mode,and the interconversion of the two is achieved by continuously regulating the coupling strength and cavity mode dissipation rate.??In order to objectively distinguish between these two effects,the paper verifies the reliability of the Bayesian Information Criterion(BIC)and the Hannan-Quinn Criterion(HQ)in distinguishing between the two phenomena,in addition to numerically comparing the magnitude of the weights of the two phenomena using the classical discriminant method of the Akaike Information Criterion(AIC).Through the research work in this paper,on the one hand,it can provide technical and theoretical reference for the further development of applications such as optical storage and slow light transmission with the aid of optomechanical system.On the other hand,the new mode discrimination criterion will be used to provide new numerical tools to understand the field features in the system.
