摘要

We study the spectrum of single-photon emission and scattering in a mixed optomechanical model which consists of both linear and quadratic optomechanical interactions.The spectra are calculated based on the exact long-time solutions of the single-photon emission and scattering processes in this system.We find that there exist some phonon sideband peaks in the spectra and there are some sub peaks around the phonon sideband peaks under proper parameter conditions.The correspondence between the spectral features and the optomechanical interactions is confirmed,and the optomechanical coupling strengths can be inferred by analyzing the resonance peaks and dips in the spectra.
