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 ξ/ ξ crit =0.01,0.5,1,2, where ξ crit =1/ 27 . (c) Absolute value of the reflection coefficient |Γ| for different coupling ratios κ/(κ+γ)=1,0.8,0.5.
