SURFACE EMITTING SEMICONDUCTOR LASER AND ITS MANUFACTURING METHOD, SURFACE EMITTING SEMICONDUCTOR LASER DEVICE, OPTICAL TRANSMITTER, AND INFORMATION PROCESSOR

摘要

A surface emitting semiconductor laser includes a substrate; a first semiconductor distributed bragg reflector of a first conductive type; an active region; a second semiconductor distributed bragg reflector of a second conductive type; a current confinement layer that confines current in the active region; an optical confinement layer that confines light in the active region; and an optical loss unit including center and periphery portions in a predetermined direction, and gives a larger optical loss to the periphery portion than that of the center portion.
