Hollow Core Fibre Group
The fabrication of hollow core fibres requires a highly skilled team.
The hollow core fibre group operate in the Zepler Institute’s £120m cleanroom facility.
We make our fibres on a dedicated fibre drawing tower.
Simulations give insight in to how these unique fibres work.
Light in shining armour.
Fibre fabrication at the ORC
Hollow core fibres made at the ORC are breaking records.
Developing diagnostic processes has enabled us to push hollow core fibre technology to new limits.

The Hollow Core Fibre Research Group

The Hollow Core Fibre research group is based in the Optoelectronics Research Centre at the University of Southampton in the UK. It conducts world-leading research on hollow core fibres, a type of optical fibre that guides light in an air core by surrounding it with a carefully constructed web of thin glass membranes. Our research encapsulates all aspects of research into these unique fibres, from theory and design through to fabrication, characterisation and application.
