An optimized optical router for mesh based Optical Networks-on-Chip

An optimized optical router is proposed in this paper for mesh-based Optical Network-on-Chip. The new 5 × 5 optical router employs lower number of microring resonators and better utilization of microring resonators based on Crux router.

1. Introduction

Networks-on-Chip (NoCs) plays an important role in improving the communication performance of multiprocessor Systems-on-Chip (MPSoC). However, as the integration scale of MPSoC increases, traditional metallic interconnects cannot satisfy the more strict requirements of high-traffic intra-chip communication. The increasing requirement of bandwidth, excessive power consumption, ultra-low transmission latency and many other problems are becoming the bottlenecks of the traditional electronic NoC. Thus the Optical NoC (ONoC) with larger communication bandwidth, lower transmission latency and lower power consumption has been widely proposed [1] [2].
