About us
Goëry Genty (Professor, Head of the research group)
I am leading the Ultrafast Photonics Group that carries out experimental, numerical, and theoretical research on ultrafast photonics and applications including:
- Ultrafast light sources with tailored properties and supercontinuum generation
- Fiber-optics and nonlinear instabilities
- Ultrafast laser dynamics, real-time characterization techniques and coherence measurements
- Ultrafast imaging and sensing
- Machine learning applications to laser design, light diagnosis, and control of nonlinear dynamics
Our research finds applications in understanding of fundamental light-matter interactions, nonlinear science as well as in the development of novel sensing and imaging approaches. Our group is always happy to collaborate and looking for talented people. Do not hesitate to contact us!
Postdoctoral Reasearcher
Francesca Gallazzi
I received my PhD from Institute of Optics-CSIC and Alcalá University in Spain, working mainly on the development of high-power mode-locked ultralong fibre lasers. Now as a postdoc in the Ultrafast Photonics Group, my work focuses on the study and real-time characterization of nonlinear ultrafast dynamics in optical fibres. I develop techniques allowing for full-field (intensity and phase) measurement of broadband optical fields with high resolution and in real-time.

My research deals with high-power multimode supercontinuum sources in the mid-infrared range and structured light. I design, construct, and characterize multi-Watt level supercontinuum sources operating in the mid-IR using various multimode soft glass fibers and different pump sources. The source can be utilized for high-resolution short-range LIDAR and bio-imaging.

Mathilde Hary
I am working on the control of nonlinear propagation dynamics in optical fibers and waveguides applying the techniques of machine learning. The ultimate goal is to generate light with characteristics tailored to particular applications in e.g. precision metrology, or high-resolution imaging and sensing. My research is at the interface of numerical simulations and experiments, and it includes international collaboration and co-supervision by Prof. John Dudley in the University of Burgundy Franche-Comté (France).
Jiaqi Li
I am working on a novel ultrafast imaging technique in the infrared that combines spatial and spectral ghost imaging with parametric conversion. My research work is involved coherence control, time-stretching, distributed Raman amplification, as well as up-conversion.
Ekaterina Krutova
I study ultrafast nonlinear phenomena in graded-index multimode soft glass fibers in the normal and anomalous short pulse regimes for the development of ultrabroadband light sources with high spectral density and beam quality applicable in absorption spectroscopy and molecular fingerprinting.
