GaAs--Al/sub x/Ga/sub 1-x/ as integrated twin-guide lasers with distributed Bragg reflectors

Journal Article · · IEEE J. Quant. Electron.; (United States)

A GaAs-Al/sub x/Ga/sub 1-x/As 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 to 2%.
