Corning, GlobalFoundries Team Up on Detachable Fiber Connectors for Silicon Photonics in AI Data Centers

Overview

• GlobalFoundries and Corning announced on Sept. 29 a collaboration to develop detachable fiber connector solutions for GF’s silicon photonics platform.
• The initial work centers on Corning’s GlassBridge glass‑waveguide edge-coupler, designed to align with v-grooves on GF’s photonics platform.
• The partners are building a vertically coupled, detachable fiber-to-PIC solution to enable multiple forms of PIC‑to‑fiber connectivity.
• Corning contributes glass materials, wafers, IOX, laser processing, and ultra-precise FAUs to reduce insertion loss, while GF provides high-volume silicon photonics manufacturing.
• Media coverage highlighted investor interest, with Jim Cramer praising Corning’s fiber optics and speculating it could replace copper in data center clusters, noting a strong recent stock rally.
