| contents | We investigate single photon transmission and the statistical properties of photon correlations in $χ^{(2)}$ microring optomechanical systems, where optical nonreciprocity is induced by directional quantum squeezing. Due to the presence of thermal phonons in the mechanical resonator, the system is highly sensitive to temperature changes. Our numerical simulations show that as the thermal phonons vary from 0 to 10, the isolation ratio of single-photon transmission decreases from 22.2 dB to 1.1 dB (or from -23 dB to -3.3 dB). Additionally, the statistical properties of photon correlations transition from exhibiting a strong bunching effect to a weak bunching effect. Moreover, the parametric amplification component enhances the device's temperature response, distinguishing it from other similar nonreciprocal devices. Our protocol suggests a potential application for nonreciprocal setups in precise temperature measurement at ultralow temperatures, thereby enriching quantum networks and quantum information processing. |
