“…Vantrease et al [6] proposed an optical interconnection network called Corona, which is a 64-radix multiwrite single read (MWSR) crossbar architecture. Many later researchers [5,[7][8][9] also proposed some other architectures based on Corona to improve the scalability of the silicon photonic network.…”

e demand from exascale computing has made the design of high-radix switch chips an attractive and challenging research field in EHPC (exascale high-performance computing). e static power, due to the thermal sensitivity and process variation of the microresonator rings, and the cross talk noise of the optical network become the main bottlenecks of the network's scalability. is paper proposes the analyze model of the trimming power, process variation power, and signal-to-noise ratio (SNR) for the Graphein-based high-radix optical switch networks and uses the extra channels and the redundant rings to decrease the trimming power and the process variation power. e paper also explores the SNR under different configurations. e simulation result shows that when using 8 extra channels in the 64 × 64 crossbar optical network, the trimming power reduces almost 80% and the process variation power decreases 65% by adding 16 redundant rings in the 64 × 64 crossbar optical network. All of these schemes have little influence on the SNR. Meanwhile, the greater channel spacing has great advantages to decrease the static power and increase the SNR of the optical network.
