Abstract
The propagation of polarized optical pulses in a birefringent nonlinear waveguide has been studied by nonlinear coupled equations which is presented in a new normalized format. It is found that the polarization coupling features of two orthogonally polarized components of the optical pulses are determined by a dimensionless parameter: the ratio of the dispersion length to the intrinsic beat length, LD/LB. When πLD/LB 1, the pulse has the same coupling features as the continuous wave, only the energy of the peak part of the pulse can couple forth and back between the two orthogonally polarized components. When 1 > πLD/LB, the perpendicularly polarized component of the pulse, i.e. instable mode, can efficiently couple to the parallel polarized component, i.e. stable mode. When πLD/LB lies in the rest region, the pulse will be significantly compressed and break into multi-peak pulses. The peaks of the pulse show different propagation speeds, thereafter the separation of the peaks increases while the pulse propagates.
