| Abstract(in English) | AlGaAs and GaInP quantum well DBR lasers consisting of a narrow ridge active channel with a window structure and a surface curved DBR grating were designed and fabricated. The quantum wells in the DBR and window regions were selectively disordered to reduce absorption loss. A high-reflectivity first-order DBR grating was adopted in the AlGaAs laser, and a long active channel was adopted in the GaInP laser to enhance the output power. The combination of the window structure and facet mirror coating improved catastrophic optical damage threshold. For both lasers, single-mode lasing with high side mode suppression ratio was obtained and the laser performance was improved under CW operation. |
