The problem of a nonreciprocal phase shifter is solved analytically in the framework of first-order perturbation theory. The expression for the differential phase shift Δβ is valid for any set of material parameters. It is shown that an optimal Δβ is achieved for a film thickness smaller than that for maximal power confinement. Using scaled parameters and introducing a normalized nonreciprocal phase...
