This paper theoretically investigates the dependence of the performance of dual-pump degenerate phase-sensitive amplification (PSA) on wavelength allocation. A fiber-based PSA under unsaturated-gain conditions is considered. Phase mismatch is formalized in terms of incident light frequencies, taking the nonlinear phase shift into account, based on which PSA performances, such as signal gain, noise figure, and phase-clamping effect, are evaluated as a function of the signal wavelength. The results quantitatively indicate that these PSA properties are degraded as the signal wavelength is detuned from the phase-matched condition.
