Research fields
The Optics Research Group performs research in:
- high resolution imaging and sensing,
- Highly sensitive optical metrology,
- new optical sources and detectors, in a wide wavelength range from x-rays to THz and with high application potential.
Scientific and technical breakthroughs are achieved by using and developing
- opto-electronic devices to actively and adaptively shape and steer electromagnetic fields;
- new optical materials and resonant structures (e.g. hyperbolic media, graded index materials)
- computational optics and artificial intelligence to extract optimum information from measured data.
Imaging
Through an optical system an image can be formed. But how to improve its resolution? Is there a limit? Can we reduce the number of optical elements with the same results? Can we even obtain an image without any lens? Here are some questions we are eager to solve.

TopicNanoTech & Light wave control
One can easily change the light path with a mirror, but there is more than direction in the light: phase, polarisation, amplitude. All these parameters can now be mastered to obtain stronger focus in microscopy, controlled enhanced fields for energy harvesting or better illumination for your street.

TopicSensing & Metrology
How to sense and measure what is too small to be directly measured with light. We develop novel techniques and instruments to perform better and smarter sensing and more accurate measurements. Sensitive detector based on superconductor, smart optical design, artificial intelligent in scattering data are some of the examples.
