Abstract:
1. A light emitting device comprising: a first layer that generates light by injection current, and forms a waveguide for 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 has a first region having an elongated linear shape, an elongated second region, and an elongated third region, the first region and the second region connect at a first reflection part provided at a first side surface of the first layer, the first region and the third region connect at a second reflection part provided at a second side surface of the first layer different from the first side surface, the second region and the third region extend to a third side surface of the first layer which is an output surface that is different from the first and second side surfaces, a longitudinal direction of the first region is parallel to the output surface, and a first light output from the second region at the output surface and a second light output from the third region at the output surface are output parallel to one another.
