Photonics Forces A Chiplet Rethink

Key Takeaways : Photonics changes chiplet design from a placement problem into a multi-physics co-design problem because thermal, mechanical, electromagnetic, and optical effects interact bidirectionally. The closer optical chiplets move to compute silicon, the more bandwidth and power improve — but the harder it becomes to manage heat, stress, alignment, and reliability. Chip architects should start with traffic patterns, system architecture, and verifiable interface contracts before deciding w
