Breakthrough in Silicon Photonics by TSMC
TSMC is advancing its silicon photonics strategy, achieving integration of co-packaged optics (CPO) with advanced packaging technologies, and is set to revolutionize AI and High-Performance Computing (HPC) applications. With sample deliveries slated for 2025 and mass production of 1.6 terabits per second products by late 2025, this shifts from electrical to optical transmission, addressing interconnect limitations like signal interference and overheating. Key collaborations with Broadcom and NVIDIA include integrating CPO into NVIDIA’s GB300 chips and future Rubin architecture, overcoming NVLink, a high-speed interconnect technology developed by NVIDIA, constraints. However, challenges like low yield rates in CPO module production might lead TSMC to outsource optical engine packaging.
My Take
This breakthrough highlights a tipping point for AI and HPC performance. Companies leveraging TSMC’s CPO solutions early could gain a competitive edge in optimizing AI workloads, emphasizing the growing need for cross-discipline expertise in photonics and semiconductor packaging.
