| titleOfInvention | Distributed feedback laser |
| abstract | The invention discloses a distributed feedback laser, which limits the longitudinal extension of a current carrier by utilizing a longitudinal current carrier blocking region, so that the active and passive layers form an inactive region corresponding to the part of the longitudinal current carrier blocking region, the effective length of the active region is reduced, the heat generated by the active region is reduced, the influence of thermal effect on the performance of the laser is further reduced, the limitation of the current carrier-photon resonance frequency in the distributed feedback laser on the direct modulation bandwidth is also effectively eliminated, and the manufacturing process is simple; meanwhile, the cavity length of the resonant cavity of the laser is not changed, so that the problem of difficult dissociation caused by shortening the cavity length is solved. |
