Buried stripe-structure semiconductor laser

摘要

A semiconductor laser and a method of producing the same wherein the semiconductor laser is produced by forming a stripe-shaped projection on the surface of a semiconductor substrate, and forming multilayered thin films with a double heterostructure including an active layer on said semiconductor substrate by using the metal organic chemical vapor phase epitaxial growth method or the molecular beam epitaxial growth method. Thus, a buried stripe-structure semiconductor laser can be produced by a sequence of crystal growth processes.
