Fabrication of silica based optical fibre has been the core of the ORC’s fibre research since the formation of the ORC. Silica optical fibre and devices made from these types of fibre form the majority of the components used in the optical telecommunications industry as well as many other uses in high power lasers, sensing, light transmission etc.
At the ORC we have access to a multi-million pound cleanroom equipped with several systems for fabrication and research on most aspects of silica fibres. The work of the fibre fabrication group is interdisciplinary. Candidates to work in this group require a background in any one of materials science, physics, engineering and chemistry.

The Fibre-Optic Gyroscope (FOG) is a well-established technology used in high-accuracy navigation and pointing applications. An interferometric sensor, the FOG uses a long fibre (often more than 1km) wound into a teacup-sized coil to precisely measure rotation via the Sagnac effect. While FOGs represent a significant fraction of the high-performance navigation market, their basic design has been relatively unchanged for over 25 years. However, recent advances in fibres at the ORC promise to vastly improve the state-of-the-art in FOG design and substantially reduce many of the optical errors that currently limit performance.
The focus of this project is to develop these fibres, optimize them for deployment in FOGs, and explore novel sensor architectures enabled by the improved fibre capability. As FOG technology encompasses a broad range of fields including fibre optics, electro-optics, signal processing, mechanical engineering, etc., this project affords the opportunity for both inter-disciplinary research within the university and close collaboration with industry partners.
