Panzer: A 6 × 6 photonic router for optical network on chip

Abstract

Photonic interconnection network plays an increasingly significant role in on-chip microarchitecture. As the heart of optical network on chips, the photonic routers implement the function of routing package from input ports to output ports. In this letter, we proposed Panzer, a 6 × 6 optical router to meet the extension demand of on-chip network. Compared with other routers, Panzer has the lowest insertion loss and the fewest number of microring resonator. We simulated the 64-core improved mesh built with Panzer, and showed the end-to-end delay and network throughput under neighbor traffic patterns.
