Анотація In this study, we investigated numerically the effect of aluminum concentration, temperature and well width on optical gain GaN / AlxGa1 – xN quantum well lasers, taken into account effective mass approximation. The numerical results clearly show that the increasing of well width, and decreasing of temperature and Aluminum concentration, the optical gain increases.
