An integrated two-wavelength semiconductor laser consisting of two DBR lasers and a Y-branch waveguide amplifier was designed and fabricated. Two-wavelength oscillation with same output level of ~10 mW and wavelength difference of 1.0 ~ 3.7 nm was obtained. Coherent THz wave generation was also demonstrated by photomixing of the integrated two-wavelength laser output.
