Inverse-Designed Ultra-Compact Passive Phase Shifters for High-Performance Beam Steering

Inverse-Designed Ultra-Compact Passive Phase Shifters for High-Performance Beam Steering

Ultra-compact passive phase shifters are inversely designed by the multi-objective particle swarm optimization algorithm. The wavelength-dependent phase difference between two output beams originates from the different distances of the input light passing through the 4 μm × 3.2 μm rectangular wavegu...
