Numerical study of the polarization proprieties in a ring cavity with total polarization control

We report the numerical study of the polarization properties of a net anomalous dispersion ring cavity with total polarization control. As a mode locker, we use the nonlinear polarization rotation (NPR) method. The initial ellipticity and azimuth were fixed to 13° and 0°, respectively. The simulations, made by the split-step Fourier method, show changes in polarization with respect to initial conditions, after the mode-lock process such as previously reported in the literature. It was found that polarization changes are caused by non-linear birefringence. The pulsed laser produces solitonic pulses with 0.4 ps FWHM and 240 W peak power.
