Abstract
An edge emitting solid state laser and method. The laser comprises at least one AlInGaN active layer on a bulk GaN substrate with a non-polar or semi-polar orientation. The edges of the laser comprise {1 1−2±6} facets. The laser has high gain, low threshold currents, capability for extended operation at high current densities, and can be manufactured with improved yield. The laser is useful for optical data storage, projection displays, and as a source for general illumination.
