Circuit-switched on-chip photonic interconnection network

In this paper, we propose a novel circuit-switched on-chip photonic interconnection network (CSPIN) architecture. Different from existing circuit-switched photonic networks, CSPIN eliminates the electronic control layer but employs optical signaling to control the circuit switching functions. To implement CSPIN, the CSPIN router is proposed which uses electro-optical tuned micro-ring resonators. The analysis based on the synthesis result of the CSPIN router shows that significant savings in power and path-setup latency are achieved by the proposed CSPIN architecture.
