Abstract：

A　new　device　of　two　parallel　DFB　lasers　integrated　monolithically　with　Y-branch　waveguide　coupler　was　fabricated.　There　was　little　difference　between　the　frequencies　of　the　two　laser　modes　because　of　the　respective　work　condition.　Optical　microwave　signal　was　generated　when　frequency　beating　of　the　two　laser　modes　was　happened　in　the　Y-branch　waveguide　coupler.　Continuous　tuning　optical　microwave　signal　from　13GHz　to　42GHz　were　realized　when　adjusting　independently　the　driving　currents　injected　into　the　two　DFB　lasers.
