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!

My research focuses on light propagation and nonlinear beam dynamics in multimode optical fibers, particularly beam self-cleaning and mode evolution in graded-index fibers. I investigate how nonlinear effects and intermodal interactions reshape the spatial and spectral properties of light, aiming to achieve controlled generation of high-quality structured light for imaging, sensing, and nonlinear light sources.
Zahra Eslami
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.
