Abstract

Arrayed Waveguide Grating Router (AWGR) is currently one of the most promising components in data center interconnections for its passive and non-blocking feature. However, the scalability is restricted by the limited channel count. In this paper, by using multiple free spectral ranges (FSRs) of AWGR and couplers, we report a novel data center architecture with extended frequency range. By simulation, we prove that, with limited FSRs, tens of thousands port count data center can be realized using a single 32 × 32 AWGR with less than 1 ms average delay and less than 0.1% blocking rate.
