Patent ID: 7991035

Claim:
A surface emitting laser array, comprising: at least two surface emitting lasers formed on a substrate, each having a laminated structure of multiple semiconductor layers including a semiconductor multilayer minor, an active layer, and a photonic crystal having a refractive index profile in an in-plane direction, the photonic crystal and the semiconductor multilayer minor in the laminated structure forming a waveguide for guiding light in a resonance mode; a region without the photonic crystal provided between adjacent surface emitting lasers in the surface emitting laser array; and an absorber of laser resonant light, provided between the at least two surface emitting lasers on a side opposite to the substrate when seen from the active layer of any of the at least two surface emitting lasers, wherein the adjacent surface emitting lasers have a same semiconductor multilayer mirror and a same active layer, and wherein the waveguide is an in-plane resonant waveguide.
