Current trends in high performance micro-processor systems suggest that the interconnection needs of NoC(Network-on-Chip)are increasing, as the scale of systems and the number of nodes become larger. Traditional electrical interconnection has the disadvantages of low bandwidth and high latency, which make it hardly meet the requests of NoC in the future. Optical interconnection is an emerging technology in recent years which is based on silicon-photonic devices. Taking light wave as message carrier, it owns...
