摘要: A semiconductor laser excelling in current injection efficiency. There is provided an inner stripe type comprising p-type cladding layer (309) having a superlattice structure composed of, alternately superimposed on each other, GaN layers and Al0.1Ga0.9N layers. The has portion of high dislocation density low density. That is, the relatively region right above constriction (308), while opening (308).
