ABSTRACT:
An improved two-dimensional semiconductor surface-emitting laser array is described in which two intra-cavity internal reflecting surfaces are formed at a 45.degree. angle to the plane of the active layer of the semiconductor laser so as to internally reflect light from each end of the active layer in a direction normal to the plane of the active layer with a buried reflective mirror provided in the path of one of said reflections, so as to transmit reflected light back through the laser and out the top surface of the array.
