| Popis: | We demonstrate a distributed reflector (DR) laser with the distributed feedback (DFB) section and the distributed Bragg reflector (DBR) section sharing the same multiple-quantum-well structure. The DR laser exhibits a stable dynamic single-longitudinal mode characteristic. A direct modulation bandwidth of 27 GHz is obtained through the detuned-loading effect and photon–photon resonance effect. The fabrication process of the DR laser is simplified due to the identical active layer structure and the uniform grating in the DFB and DBR sections. |
