Based on different basic routing elements, device architectures and design schemes of three kinds of four-port optical routers with the same routing function are studied. First, the structural parameters of the routing elements including cross-coupling one microring resonator (CCO-MRR), cross-coupling two microring resonators (CCT-MRR) and parallel-coupling one microring resonator (PCO-MRR), are optimized for single-mode transmission, low optical loss and phase-match between microring waveguide and channel waveguide. Then, detailed routing topologies of the three routers are presented, and a thorough comparison among them is made on their routing performances. The used MRR numbers of the CCO-MRR-based and PCO-MRR-based routers (four rings) are half of that of the CCT-MRR-based router (eight rings); the PCO-MRR-based router depicts the minimum insertion loss (0.02–0.6 dB); the CCT-MRR-based router reveals the minimum crosstalk (
