Nature Electronics review maps co-packaged optics for AI compute interconnects
jwt0625 · x · 2026-08-22
Researchers affiliated with SK published a review in Nature Electronics, "Co-packaged optics for high-performance computing and artificial intelligence," surveying CPO: resistive losses, capacitive loading and frequency-dependent distortion increasingly constrain bandwidth, latency and energy efficiency in electrical interconnects, while co-packaged photonic channels promise low propagation loss, high bandwidth and superior signal integrity.
The poster calls it a great read for getting familiar with CPO, though with quite a few minor errors — and notes it's mostly AI-generated, so you'd better feed it to your own AI to extract key points. They also lament that education in 2026 still happens via static PDFs and float the idea of an interactive illustration with real examples across the stack.
