Making On-Chip Photonics Manufacturable
By Gregory Haley - 18 Jun, 2026 - Comments: 0

Key Takeaways: System-level energy and bandwidth pressures are pulling optics into the package faster than the manufacturing flow can mature. Photonics combines front-end fabrication, materials, thermal, cleanliness, and test into one problem that can’t be solved domain by domain. Test is moving upstream because discovering an optical failure after final assembly forfeits every goo... » read more

All AI Data Center Interconnects Will Be Optical Within 5 Years
By Geoff Tate - 06 Apr, 2026 - Comments: 0

I spent several days at OFC (Optical Fiber Communications Conference) 2026 in LA. The crowds were huge and the enthusiasm intense. Long-time attendees noted the shift from telecom to data center AI in just a few years. Nvidia GTC 2026 took place simultaneously in San Jose. OFC and GTC are entangled because data center AI needs optical interconnect to keep compute fed. Optical interconnect... » read more
