Abstract:
1. A nitride semiconductor light-emitting device formed from a nitride semiconductor wafer comprising a plurality of nitride semiconductor layers disposed on top of a nitride semiconductor substrate, wherein the nitride semiconductor substrate is a GaN substrate having, in a surface thereof on which the plurality of nitride semiconductor layers are disposed, wherein the surface of the nitride semiconductor substrate on which the plurality of nitride semiconductor layers are disposed has a C plane wherein the nitride semiconductor light-emitting device has, between the plurality of dislocation concentrated regions, a laser light guide region formed in the parallel direction, and wherein the nitride semiconductor light-emitting device is cut out of the nitride semiconductor wafer and has, as end surfaces of a cavity, cleavage planes perpendicular to the laser light guide region.
