Surix: Non-blocking and low insertion loss micro-ring resonator-based optical router for photonic network on chip

摘要

Photonic network-on-chip is utilized as a candidate paradigm for important attributes such as high bandwidth and low energy consumption. In this paper, a non-blocking five-port photonic router is proposed for the 2-D mesh topology, which is called Surix. Surix has been designed for improving the physical layer and the network's performance parameters in multi-core network topologies. Moreover, a new routing algorithm on Surix is proposed, in which turning models and the circuit switching method are used for mitigating photonic insertion loss and power consumption of the photonic layer. The proposed algorithm can select various source and destination nodes through the selected routes with the lowest insertion loss and power consumption. The simulation results show that Surix outperforms conventional routers in network performance parameters. For instance, the insertion loss of Surix in the mesh topology shows a 9.92-37.15 percent improvement compared to conventional routers.
