Microsoft Acquires Hollow-Core Fiber Innovator Lumenisity

Facebook Twitter LinkedIn Email
Microsoft has acquired Lumenisity Ltd., a supplier of next-generation hollow-core fiber (HCF) solutions. The acquisition will expand Microsoft’s ability to further optimize its global cloud infrastructure and serve customers with strict latency and security requirements.

Lumenisity’s HCF technology can provide benefits across a broad range of industries including health care, financial services, manufacturing, retail, and government. Organizations in these sectors could see significant benefit from HCF solutions as they rely on networks and data centers that require high-speed transactions, enhanced security, increased bandwidth, and high-capacity communications.

Potential rollouts for HCF technology span the public sector, where HCF could provide enhanced security and intrusion detection for federal and local governments worldwide. In health care, because HCF can accommodate the size and volume of large data sets, it could help accelerate medical image retrieval, facilitating providers’ ability to ingest, persist, and share medical imaging data in the cloud. In addition, with the rise of the digital economy, HCF could help international financial institutions seeking fast, secure transactions across a broad geographic region.

Lumenisity formed in 2017 as a spinoff from the Optoelectronics Research Centre at the University of Southampton. Lumenisity’s HCF technology uses a proprietary design in which light propagates in an air core, providing a 47% boost in speed compared to traditional silica glass fiber optic cables. Lumenisity’s HCF solutions also enables lower costs, increased bandwidth, and enhanced network quality due to elimination of fiber nonlinearities and broader spectrum. The technology also offers the potential for ultralow signal loss enabling deployment over longer distances without repeaters.

The company is well known for its nested anti-resonant hollow-core fibers (NANFs) — hollow-core fibers that rely on thin glass membranes surrounding the core to hold light in their central voids — and Lumenisity bills its core technology as its NANF CoreSmart HCF cable.

In a  2020 research paper, Southampton researchers introduced three HCF designs with comparable attenuation to silica fibers between 600 and 1100 nm. The significance of application around the 660-, 850-, and 1060-nm wavelengths ties into a range of potential quantum- and semiconductor-based applications, including quantum computing and short-reach data transmission.

Smallest amount into which the energy of a wave can be divided. The quantum is proportional to the frequency of the wave. See photon.
A sub-field of photonics that pertains to an electronic device that responds to optical power, emits or modifies optical radiation, or utilizes optical radiation for its internal operation. Any device that functions as an electrical-to-optical or optical-to-electrical transducer. Electro-optic often is used erroneously as a synonym.
