Continuous-mode photon-phonon entanglement effects in optomechanical resonator-waveguide system

Abstract We study the quantum effects of entanglement between continuous-mode photon and phonon fields in waveguide channels that are coupled to an optomechanical resonator structure with two optical modes. We show that such optomechanical resonator-waveguide system can drastically enhance the efficiency for generating entangled traveling photon-phonon single pairs, and can serve to implement controllable continuous-mode photon-phonon squeezing of weak input signals. The effectiveness of the generation-efficiency enhancement and the quantum squeezing operation is attributed to the resonance between the normal-mode photon transition and the phonon mode in the optomechanical resonator structure.
