We show that the inclusion of junction-heating effects in the numerical modeling of a gain-guided diode laser array produces significant changes in the mode characteristics of such devices. This is evidenced as alterations in the near- and far-field emission patterns and modal gains of the high-order array eigenmodes. Our experimental measurements of the emission patterns from free-running and injection-seeded gain-guided diode laser arrays show very good agreement with the results of our model and illustrate the influence of these thermal effects.
