摘要

Based on calculation of energy structures and dipole transition matrix elements,theoretical calculation and analysis of polarization dependent optical gain and gain saturation are given for GaN quantum well lasers to investigate the characteristics of nonlinear gain.In turn,the linear spectra and self saturation spectra of TE and TM modes are given.The effect of energy structure and carrier sheet density on gain and self saturation is analyzed.
