In class, we have shown that the parametric gains for the signal wave, g, and the idler wave, g′, satisfy g′ =g−1, when the two waves are degenerate in frequency and are not subject to any linear loss. Does this relation still hold for Γs ≠0? Why?

Nonlinear optics In Lecture 11, we analyzed nondegenerate optical parametric ampli cation (NOPA) under the undepleted-pump approximation and assuming no linear loss for all lightwaves involved. In practice, however, the linear losses could be significant. Let Γs and Γi be the linear loss coefficients per unit length for the signal and the idler waves, respectively, […]
