摘要

An integrated two-wavelength distributed Bragg reflector (DBR) laser consisting of two DBR lasers and a Y-branch waveguide amplifier was designed and fabricated. The optical waves from the two DBR lasers are combined into a single output channel of the Y-branch waveguide amplifier and emitted from the output facet. Laser performances of the same output level of ~10 mW and a wavelength difference of 1.0-3.7 nm (0.47-1.8 THz beat frequency) with a side-mode suppression ratio of 30 dB were obtained. Coherent THz wave generation was also demonstrated by photomixing of the integrated two-wavelength laser output.
