摘要

A voltage-driven InP/InGaAsP 1 × 2 optical switch based on multimode interference (MMI) is proposed and numerically studied. In plane shift of the optical field across the output cross-section of a multimode waveguide enables optical switching between two symmetric output waveguides. Two twin electrodes on top of the multimode waveguide are tuned with reverse bias voltage to switch output port by ...
