Abstract

We designed a type of evanescent taper coupler for micro-transfer printed III-V photonic devices with high coupling efficiency (CE) and good manufacturing tolerances. The primary sensitive factor in the manufacturing process, lateral misalignment, is incorporated into the particle swarm optimization algorithm. The CE of the optimized taper structure exceeds 98.5% for a misalignment of up to 0.5 microns within a taper length of 150 microns. Furthermore, the taper structure demonstrates robust coupling under other manufacturing tolerances.
