8 ÿ 8 passive noblocking microring resonator crossbar for on-chip WDM-based interconnection network

Abstract

We use the transfer matrix method to investigate a 8ÿ8 no blocking microring resonator crossbar that can be used to route wavelength division multiplexing (WDM) signals across the chip. The proposed design is no-blocking and reconfigurable and its salient feature is the ability to support multicasting and multiplexing efficiently, which can be satisfied for on-chip interconnects in future many-core processors.
