Abstract:
1. A GaN-based laser device having a GaN-based semiconductor stacked-layered structure including a light emitting layer, wherein said semiconductor stacked-layered structure includes a stripe-shaped waveguide formed therein and has two side surfaces opposite to each other to sandwich said stripe-shaped waveguide in its width direction therebetween, at least one of said two side surfaces is disposed off a chip-division line along which said device has been cut off, at least a part of said at least one of the two side surfaces including a plurality of partial side surfaces tilted with respect to a longitudinal direction of said stripe-shaped waveguide, and in plan view of the laser device one end of the light emitting layer lies on the side surface with the tilted partial side surfaces and another end of the light emitting layer lies on another of the two side surfaces.
