Input-output model. (a) Schematic of the input-output model used for calculating the response of the parametric amplifier in the presence of additional loss modes. (b) Normalized pump field photon number n in the resonator as a function of reduced pump frequency δ for effective drive strengths , where . (c) Absolute value of the reflection coefficient for different coupling ratios .
