Stability of the horizontal transverse modes of the planar stripe lasers with deep Zn-diffusion
Abstract
It has been found experimentally that the planar stripe lasers with deeper Zn-diffusion have more stable horizontal transverse modes. A simple equivalent circuit model is proposed that can explain why the planar stripe lasers with deep Zn-diffusion have stable horizontal transverse modes. It is shown analytically that the narrowing of gain-induced guide of planar stripe lasers with undoped active layer and deep Zn-diffusion is responsible for the stabilization of horizontal transverse modes.
