This paper presents the results of a thermal computational analysis of a two-dimensional laser array emitting from a surface. The array consisted of eight equispaced ridge-waveguide edge-emitting nitride diode lasers. Surface emission of light was obtained using mirrors inclined at 45°. The authors investigate how the geometrical dimensions of the array emitters and their pitch in the array affect the increase and distribution of temperature in the device. They also examine the influence on the temperature increase and distribution of the thickness of the insulating SiO₂, the thickness of the gold layer forming the top contact of the laser, and the thickness of the GaN substrate, as well as the influence of the ridge-waveguide width.
