Abstract:
1. A surface-emission laser diode, comprising: a GaAs substrate; a cavity region formed over said GaAs substrate, said cavity region including at least one quantum well active layer producing a laser light and harrier layers; and an upper reflector and a lower reflector provided at a top part and a bottom part of said cavity region over said GaAs substrate, said upper reflector and/or lower reflector including a semiconductor distributed Bragg reflector, at least a part of said semiconductor distributed Bragg reflector comprising a low refractive index layer of Al one of said low refractive index layers constituting said upper reflector and/or said lower reflector and located closest to said active layer comprising (Al an interface between said cavity region and said low refractive index layer of said upper reflector and/or said lower reflector located closest to said active layer being coincident to an anti-node of an electric strength distribution.
