| Abstract: | 1.55-μm InGaAsP-InP two-section DFB lasers with varied ridge width, both gain-coupled and index-coupled, have been fabricated. Self-pulsations with frequencies around 40 GHz are observed. The related mechanism and the tunability of generated self-pulsations is studied. |
| Keywords: | generation DFB lasers related mechanism tunability ridge width |
