  • Abstract
    A GaAs-AlxGa1-xAs integrated twin-guide (ITG) laser with distributed Bragg reflectors (DBR) was fabricated. The DBR was in the form of a third-order grating which was chemically etched on the surface of the output waveguide. The ITG lasers with distributed Bragg reflectors (DBR-ITG lasers) operating at room temperature showed single mode oscillation up to 1.5 times the threshold current and the half-side external quantum efficiency was 1 ∼ 2 percent.
