Prof. Radan Slavik, born 1973, completed his PhD from Charles University in Prague in 2000. From 2000 to 2003, he worked as a postdoctoral research fellow at the Centre for Optics, Photonics and Lasers of Université Laval, Canada, before joining the Institute of Photonics and Electronics of the Czech Academy of Sciences as a senior research scientist. In 2009, he joined the Optoelectronics Research Centre at the University of Southampton, where he became a professor in 2019 and currently serves as Deputy Head of School for Research. In 2018, the Optical Society of America (OSA) accepted him as a Fellow for his  “…pioneering work in high-speed optical signal processing using fiber gratings, optical injection locking and phase-sensitive amplification for applications in high-capacity fiber optic communications and information processing.” He was also elected as a Fellow of IEEE. His notable honours include the Otto Wichterle Award (2006), the Visegrad Group Academies Young Researcher Award (2007), and the Tribute Award from the Centre d’Optique, Photonique et Laser (2025).

       Hollow core optical fibres are emerging as next-generation optical fibre for telecommunications. Their unique properties, however, can be beneficial for significantly wider range of applications, including stable interferometers and optical references. The talk will summarize key requirements for making optical references from hollow core optical fibres and discuss state-of-the art, comparing them to other emerging technologies for this application. The lasers stabilized to stable fibre interferometers are of interest for a range of applications including frequency metrology, low-noise RF signal generation, or low-frequency (e.g. seismic) sensing.
