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.
