Patent ID: 8894211

Claim:
A light emitting device comprising: a first layer that generates light by injection current and forms a waveguide of the light; a second layer and a third layer that sandwich the first layer and suppress leakage of the light; and an electrode that injects the current into the first layer, wherein the waveguide of the light obtained by the electrode has a belt-like first region and a belt-like second region, the first region has a first part with curvature, the second region has a second part with curvature, the first region and the second region are connected in a reflection part provided on a side surface of the first layer, and a first light is output from the first region on an output surface which is a side surface of the first layer opposed to the side surface on which the reflection part is provided, a second light is output from the second region on the output surface, and the first and second light are output in the same direction.
