Novel 2×2 wide-angle AlGaAs/GaAs carrier-injection optical switch with reduced power consumption

We demonstrate a 2×2 AlGaAs/GaAs optical switch based on our wide-angle design including current-spreading restriction, curved electrodes, double-reflection interfaces, and graded heterojunctions. The fabricated device has a 7° crossing angle and a 0.6W power consumption.
