Abstract

We proposed a compact and longitudinally zig-zag shaped 1x4 power splitter using particle swarm optimization algorithm integrated with the finite-difference time-domain method. Different particle sizes in the algorithm are tested and splitter structures with high uniformity (less than 0.04 dB) and small insertion loss (less than 0.40 dB) are achieved over a wide bandwidth. Our designs show the best performance with low insertion loss and high uniformity comparing to the existing ones, while it can be fabricated with industry-standard lithography due to its unit cell length of 100 nm or more.
