Abstract
Three types of quasi-stadium laser diodes, which have confocal, concentric, and geometrically unstable end mirrors, were fabricated by a reactive-ion-etching technique. It is shown that the experimental results on the lasing characteristics of these lasers excellently correspond to the theoretical results by the extended Fox–Li mode calculation method. The morphological effects on lasing modes are discussed from the viewpoint of ray-wave correspondence.
