LIGHT EMITTING DEVICE, SUPER LUMINESCENT DIODE, AND PROJECTOR |
| 摘要 |
A light emitting device includes: an active layer; and a first cladding layer and a second cladding layer that sandwich the active layer, wherein the active layer forms an optical waveguide that guides light, a traveling direction of the light guided in the optical waveguide changes at a first reflection part provided on a first side surface of the active layer, and the first reflection part is located outside of a region in which the first cladding layer and the second cladding layer are provided in a plan view. |
