Semiconductor distributed feedback laser device and method for manufacturing semiconductor element |
| abstract |
(57) [Summary] [Objective] In a semiconductor distributed feedback laser device having a structure for obtaining distributed light feedback by a periodic light absorption layer, sufficient distributed feedback is obtained while making the average absorption loss as small as possible. [Structure] A periodic light absorption layer is arranged outside a stripe-shaped region along a light propagation region. |
