摘要：

The　phase　modulator　is　important　in　laser　phased　array.　The　arrayed　phase　modulator　based　on　optical　waveguide　is　proposed.　The　index　profile　in　annealed　proton-exchanged　(APE)　LiNbO3　waveguide　is　studied　theoretically　and　simulated　by　beam　propagation　method　(BPM).　High　uniformity　of　output　power　is　gained　numerically　by　optimized　design　of　cascaded　Y-branch.　The　structure　with　long　electrodes　is　designed　to　obtain　low　half-wave　voltage.　The　1×4　arrayed　phase　modulator　is　finally　fabricated　using　APE　technology.　The　optical　and　electrical　properties　are　tested.　The　insertion　loss　is　6.83　dB,　the　uniformity　of　output　power　is　0.23　dB,　and　the　voltages　are　2.1,　3.4,　2.0,　and　2.1　V,　respectively,　which　indicates　that　the　arrayed　phase　modulator　can　satisfy　the　theory　and　expectation　well.
