GlobalFoundries (GF) and Corning announced a collaboration to co-develop detachable fiber connector solutions for silicon photonics platforms, targeting high-density, power-efficient optical packaging for AI data centers. The partners will demonstrate the first glass-waveguide based edge-coupler solution, Corning’s GlassBridge, at ECOC 2025 in Copenhagen and at GF’s upcoming Technology Summit in Munich.
The GlassBridge edge-coupler integrates with GF’s photonics platform v-grooves and provides detachable fiber-to-PIC connectivity. In parallel, the companies are developing vertically coupled solutions for broader co-packaged optics (CPO) architectures. Corning brings its expertise in special glass compositions, wafer and laser processing, and fiber array units (FAUs) with ultra-precise core alignment, while GF contributes its high-volume semiconductor manufacturing capabilities and established silicon photonics platform.
This collaboration aims to provide hyperscale operators with reliable, scalable coupling technologies that support scale-out and scale-up AI cluster networks. The partners emphasize that their combined supply chain strength and technology depth will accelerate the deployment of advanced optical packaging in high-performance computing and AI infrastructure.

🌐 Analysis: Detachable fiber connectors are a critical enabler for co-packaged optics, where serviceability and modularity are needed to make dense optical integration practical at scale. Corning’s GlassBridge solution, integrated with GF’s silicon photonics, represents a push toward manufacturable, field-serviceable PIC-to-fiber connectivity. As hyperscalers explore CPO for AI data centers, fiber attach and detach solutions will become essential. Competitors such as Ayar Labs, Broadcom, and Coherent are advancing different aspects of optical I/O and packaging, highlighting the strategic importance of reliable coupling technologies.
