Optical routers are the important devices responsible for node data exchange in on-chip optical interconnect networks. The latest research progress of optical routers at home and abroad are introduced. The general principle of constructing N-port non-blocking optical routers by using micro-ring resonators and Mach-Zehnder optical switches is emphatically introduced. The statistical analysis and simulation results show that the application is generally Compared with the optical routers of the same size reported before, the performance of the optical router built by the principle is improved in terms of the number of switches, insertion loss and average power consumption.
