Our group discovers new areas where optical fibres can revolutionize the field and collaborates with world-leading researchers in these areas. We also develop components needed to use these new fibres, e.g., their interfacing to existing systems.
As well as this, we specialize in time and frequency metrology, working closely with the National Physical Laboratory (NPL), benefiting from emerging technologies such as Optical Frequency Combs. We study how improved timing accuracy will improve a range of applications from telecom/datacom to navigation, and fundamental physics (e.g., gravitational waves detection, quantum, study of chemical reactions, etc.).
Specific topics of interest are:
- Distributed measurement techniques along fibres mainly for their characterization, but also applicable to distributed sensing
- Studying components made of hollow core fibres such as high-finesse Fabry-Perot resonators
- Evacuation of hollow core fibres to enhance their performance in selected applications such as ultrastable fibre interferometers
- Hollow core fibres with reduced sensitivity to environment changes (temperature, vibration, acoustic) and their applications
- Ultra-stable fibre interferometers and lasers (“stable optical oscillators”) locked to these stable references
- Timing and frequency distribution for high-resolution ranging, spectroscopy, microwave generation, astronomy, geodesy, sensing, etc.
- High-fidelity generation and transmission of THz signals
