LIGHT-EMITTING DEVICE HAVING A GAIN REGION AND A REFLECTOR
First Claim
1. A light-emitting device comprising:
- a first cladding layer;
an active layer formed above the first cladding layer;
a second cladding layer formed above the active layer;
a gain region, which generates light by applying a voltage, provided at a portion of the active layer; and
a reflecting part reflecting the light generated in the pain region, whereinthe active layer has a first side surface and a second side surface that are parallel to each other,the gain region has a first end surface disposed on the first side surface, and the gain region has a second end surface disposed inside from the second side surface side and angled relative to the first side surface,the second end surface, the gain region and the first end surface are provided in a first normal direction relative to the second end surface, andthe reflecting part is disposed next to the second end face.

Abstract
A light-emitting device has a first cladding layer, an active layer formed above the first cladding layer, a second cladding layer formed above the active layer, a gain region, and a reflecting part. The active layer has first and second side surfaces parallel to each other. The gain region has a first end surface disposed on the first side surface. The gain region also has a second end surface disposed inside from the second side surface and angled relative to the second side surface. The second end surface, the gain region and the first end surface are provided in a first normal direction relative to the second end surface. The reflecting part is disposed next to the second end surface.
