Measurements of the magnitude and spatial distribution of the optical gain in a stripe-geometry junction laser are related to observations of the intensity profile along the junction plane of the same laser. The width of the fundamental mode is in excellent agreement with a two-dimensional waveguide in which confinement along the junction plane is induced primarily by the optical-gain profile. The remainder of the confinement is consistent with a refractive-index profile established by a temperature distribution in the presence of defocusing by the free carriers. Within the two-dimensional model, no evidence of defocusing like that deduced previously for double-heterostructure lasers was found.
