Abstract Solutions to charge transport equations are used to illustrate the variation of the active region refractive index of the double-heterostructure GaAs laser. It is shown that a marked asymmetry can arise in the refractive index. In this paper, a suitable waveguide theory is developed to take account of this effect. The necessity for such a waveguide theory is demonstrated by comparing threshold current densities and far-field patterns calculated with this model to those calculated using a simpler waveguide model.
