Abstract: Optical network-on-chip(ONoC) has many characteristics superior to electrical interconnection and has emerged as a promising alternative. To improve the performance of optical on-chip networks, a novelring-based 4×4 nonblocking silicon optical router was proposed by means of optical module method.This structure just composes evenmicroring-resonator-based switching elements and six waveguide crossings,which reduce power consumption, device area and insertion loss. Finally, the topology performance were evalutated in terms of insertion loss and power consumption. The simulation results demonstrate that the proposed architecture consumes 8% less power and 7%less optical insertion loss.
