Abstract:
1. A light emitting device comprising: an active layer forming a gain region that generates light; a first cladding layer and a second cladding layer that sandwich the active layer and confine the light in the active layer; and a first reflective part and a second reflective part that are provided next to the gain region so as to reflect the light; wherein each of the first reflective part and the second reflective part changes a first light traveling direction of the light and a second light traveling direction of the light as viewed from a stacking direction of the first cladding layer, the active layer, and the second cladding layer, the gain region extends continuously from a first end provided at a first side surface of the active layer to a second end provided at the first side surface, and the light is emitted from the first end as first light propagating in a first light emitting direction having a first angle with respect to the first side surface, and the light is emitted from the second end as second light propagating in a second light emitting direction having a second angle with respect to the first side surface.
