Light emitting device

摘要

A light emitting device includes an active layer; at least a portion of the active layer constitutes a gain region. The gain region is continuous from a first end surface and a second end surface. The gain region includes a first portion extending from the first end surface to a first reflective surface in a direction tilted with respect to a normal to the first side surface as viewed two-dimensionally; a second portion extending from the second end surface to the second reflective surface in a direction tilted with respect to a normal to the first side surface as viewed two-dimensionally; and a third portion extending from the first reflective surface to the second reflective surface in a direction tilted with respect to a normal to the first reflective surface as viewed two-dimensionally.

主权项

1. A light emitting device comprising:
an active layer forming a gain region that generates the 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, whereineach 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, andat least one of the first reflective part and the second reflective part includes a groove filled with an insulation material.
