摘要

We demonstrate a waveguide-based polarization controller that monolithically incorporates an active InGaAlAs/ InAlAs multiple-quantum-well phase shifter and a passive half-ridge polarization converter on InP. The butt-joint active/passive integration technique and self-aligned waveguide fabrication steps are employed. Using the fabricated device, efficient rotation of the Stokes vector over π radi...
