We demonstrate theoretically and experimentally that two orthogonal polarizations of light see an unequal index contrast in a UV-induced fiber Bragg grating. We have found that in a Bragg grating the phase-velocity mismatch is a function of detuning, and hence we can introduce an effective birefringence. The description of the polarization dynamics that we developed was confirmed by a set of experiments with a fiber grating. We show theoretically that by adjusting the value of the unequal index contrast relative to the average birefringence it should be possible to eliminate the phase-velocity mismatch between polarizations at a given frequency. |
