Implementing Optical Pass-Through Links via Photonics Crossbar Chip for HPC Applications

We propose an ultra-compact silicon photonics (SiPh) crossbar chip for implementing optical pass-through (OPT) links for high performance computing applications. We conduct high-speed measurements for a single-wavelength OPT link and evaluate the bit error rate performance from 8 Gbps to 32 Gbps under the effect of an aggressor channel as well.
