Laser structure with distributed feedback and method of manufacturing same.

摘要

Laser structure with varying distributed feedback, comprising: a substrate (1); an active layer applied to the substrate (2); a first cladding layer applied to the active layer (3); a second cladding layer (4) applied to the first cladding layer; and variation means (6) for varying a coupling coefficient between the wave travelling backward and forward in the active layer such that a relatively uniform power density is obtained in the active layer. <IMAGE>
