| contents | Fully Homomorphic Encryption (FHE) facilitates secure computations on encrypted data but imposes significant demands on memory bandwidth and computational power. While current FHE accelerators focus on optimizing computation, they often face bandwidth limitations that result in performance bottlenecks, particularly in memory-intensive operations. This paper presents OptoLink, a scalable photonic interconnect architecture designed to address these bandwidth and latency challenges in FHE systems. OptoLink achieves a throughput of 1.6 TB/s with 128 channels, providing 300 times the bandwidth of conventional electrical interconnects. The proposed architecture improves data throughput, scalability, and reduces latency, making it an effective solution for meeting the high memory and data transfer requirements of modern FHE accelerators. |
