Switching between linearly polarized states of slightly different optical frequencies is found in the fundamental transverse mode pattern is described as the injection current is increased. Polarization switchings obtained here as the injection current is increased in a semiconductor rate equation model incorporating a vector electric field, birefringence and the linewidth enhancement factor, are similar to previously reported experimental results for the fundamental mode.

Abstract
Switching between linearly polarized states of slightly different optical frequencies is found in the fundamental transverse mode pattern is described as the injection current is increased. Polarization switchings obtained here as the injection current is increased in a semiconductor rate equation model incorporating a vector electric field, birefringence and the linewidth enhancement factor, are similar to previously reported experimental results for the fundamental mode. Polarization properties of higher order Gauss-Hermite modes are also analyzed.
