摘要: A semiconductor laser includes a semiconductor laser portion including an active layer portion having a p-type cladding layer, an active layer, and an n-type cladding layer on a p-type InP semiconductor substrate; and current confining structures that fill spaces on both sides of the semiconductor laser portion. Each of the current confining structures includes a first p-type InP layer, a Ru-doped InP layer, and a second p-type InP layer. The Ru-doped InP layer is in contact only with the first and second p-type InP layers. To obtain the structure, timing of introduction of a halogen-containing gas is adjusted.
