Optomechanically induced transparency in a spinning resonator

National Natural Science Foundation of China (NSFC) [11474087, 91536107]; Key Research Program of Frontier Science of Chinese Academy of Sciences (CAS) [QYZDY-SSW-SLH009]; National Key R&D Program of China [2016YFA0301504]We study optomechanically induced transparency in a spinning microresonator. We find that in the presence of rotation-induced Sagnac frequency shift, both the transmission rate and the group delay of the signal are strongly affected, leading to a Fano-like spectrum of transparency. In particular, tuning the rotary speed leads to the emergence of nonreciprocal optical sidebands. This indicates a promising new way to control hybrid light - sound devices with spinning resonators
