Semiconductor laser device |
摘要 |
The present invention relates to a semiconductor laser device comprising:
a substrate;
a first semiconductor layer of first conductivity type;
an active layer;
a second semiconductor layer of second conductivity type that is different from the first conductivity type;
a waveguide region that is formed in a stripe shape in said first semiconductor layer, said active layer and said second semiconductor layer so that current is restricted to flow in said waveguide region;
and resonance surfaces that are substantially perpendicular to said waveguide region;
wherein a plurality of recesses are formed at the surface of said second semiconductor layer in a region that is, in a plan view, apart from said waveguide region and is in the vicinity of one of said resonance surfaces. |
