An Ultra-broadband Power Splitter Designed by Topology Optimization Algorithm

An ultra-broadband, low loss and ultra-compact power splitter based on topology optimization algorithm was designed. The 1 dB bandwidth of the power splitter is about 0.96 µm from 1.32 µm to 2.28 µm, which is compatible with the next-generation communication band. The minimum insertion loss is 0.63dB.
