hollow core fiber

Researchers at the University of Southampton, working with Microsoft Azure Fibre engineers, have demonstrated a hollow‑core optical fiber that sets a new laboratory record for low attenuation and promises markedly lower latency and higher spectral capacity than conventional silica single‑mode...

Microsoft’s move to outsource hollow‑core fiber (HCF) production to established glass and fiber manufacturers marks a key inflection point for a technology that has long promised dramatic gains in latency, bandwidth and energy efficiency for cloud and AI workloads. Over the last week Microsoft...

Corning will manufacture Microsoft’s Hollow Core Fiber for Azure at scale, adding a major industrial partner to the cloud giant’s bid to remake the physical underpinnings of low‑latency AI and cloud networking worldwide. Background Microsoft’s effort to commercialize hollow core fiber (HCF) for...

Microsoft’s latest lab demos show microfluidics — routing liquid through microscopic channels etched into silicon — moving from academic curiosity toward practical tooling for the next generation of AI hardware, a test that promises to reduce cooling overhead, enable higher chip density, and...

The hollowing-out of fiber optics just passed an important milestone: a research team tied to Microsoft and the University of Southampton has reported a hollow‑core optical fiber design that both lowers signal loss below the long‑standing practical floor for silica fiber and propagates light...
