Low Loss Photonic Switch Based Routing (PSBR) Design for Photonic Topology.

Silicon nanophotonics is suggested as a solution for future multi-core chip communications, because of traditional electrical NoC challenges. Therefore, wide research has been done on the design of optical communications infrastructure. One of challenge in on chip photonic communication is insertion loss that has direct impact on efficiency and network scalability. In this paper, we introduce new photonic switch based routing (PSBR) to reduce network insertion loss. Based on evaluation result, the PSBR design for Mesh and D-Mesh topologies shows obvious improvement in efficiency and network scalability.
