In this paper,we investigate the quantum fluctuations of subharmonic reflected field from a triple-resonant degenerate optical parametric amplifier(OPA)inside coupled optical resonators,which is driven by the squeezed beam at signal frequency.By controlling the relative phase between the pump beam and the injected signal beam,we can see the quantum fluctuation in the phase direction and amplitude direction due to the parametric down-conversion process in the cavity.Thus,the phase sensitive operation of the compression field is realized due to the quantum interference be-tween the harmonic field of the down converter of OPA and the inner field of the coupled optical resonator.We veri-fied the quantum coherent phenomena of OPA in coupled optical resonators and phase-sensitive manipulations of quantum entanglement for quantum information processing.We realized the electromagnetically induced transpa-rency-like(EIT-like)effect and the optical parameter conversion process at the same time in one optical device.These properties can favor higher manipulation precision and control efficiency,which is more suitable for the integration of quantum-on-chip systems,laying a foundation for the practical application of quantum information.
