Radan Slavik

Professor Radan Slavik is a distinguished academic at the University of Southampton's Optoelectronics Research Centre (ORC) within the Faculty of Engineering and Physical Sciences. His research focuses on the generation, manipulation, and detection of optical signals carrying information through signal phase and amplitude-phase interactions. As a Professorial Fellow-Research, he leads groundbreaking work in coherent optical communications, hollow core optical fibres, and optical frequency combs.

Slavik's research interests span multiple cutting-edge domains including Coherent Optical Communications, Hollow Core Optical Fibres, Optical Frequency Combs, Ultra-stable Laser Oscillators, and Radio Frequency Photonics. His work has been pivotal in developing lightwave technologies that exploit optical phase, enabling significant advancements in internet capacity through coherent optical communications. His research on hollow core fibres has revealed their remarkable insensitivity to environmental variations, particularly temperature, which has opened new applications in seismic sensing, LIDAR calibration, and data center networks.

His publication record reveals a strong focus on hollow core fibre technology, with recent work exploring thermal stability, gas dynamics in hollow core fibres, and applications in telecommunications infrastructure. The research demonstrates increasing sophistication in measurement techniques, fibre design, and practical implementations across multiple domains including sensing, communications, and metrology.

• Fellow of OSA (2017)
• Thermally-insensitive Hollow Core Optical Fibres (2018)

Professor Slavik actively supervises multiple PhD students including Mitchell Gerrard, Win Adiyansyah Indra, Rene Andres Reynolds Hamel, Usue Irene Barbeito Edreira, Karim Elglmady, and Amalie Gjelsvik. His research is supported by significant grants from EPSRC, Royal Society, and EURAMET-EMRP-MSU, with collaborations spanning National Physical Laboratory, API Sensors Ltd., and University College London. His work on hollow core fibres with low thermal sensitivity forms a flagship research topic, comprising four distinct streams: fundamental fibre properties, new approaches to thermal stability, demonstration of low thermal sensitivity applications, and gas dynamics in gas-filled hollow core fibres.
