Many phenomena in nature, including multiple chemical and biological processes, are governed by the fundamental property of chirality. An object is called chiral when its mirror image cannot be superimposed with the original object. Many examples of chirality can be found in nature, from seashells to DNA molecules.  

 

This project will address the recently emerged new platform for nanophotonics based on high-index dielectric nanoparticles that opened a whole new realm of all-dielectric Mie-resonant nanophotonics or Mie-tronics. High-index dielectric nanoparticles exhibit strong interaction with light due to the excitation of electric and magnetic dipolar Mie-type resonances.

The project bridges the fundamental physics of topological phases with nonlinear optics. This promising synergy is expected to unlock advanced functionalities for applications in optical sources, frequency combs, isolators and multiplexers, switches and modulators, both for classical and quantum light. 

Use lasers to sculpt matter at the nanoscale! In this project you’ll create shimmering holographic patterns and functional nanostructures on metals and glasses, exploring their applications in photonics, anti-counterfeiting, and smart coatings—all while uncovering the physics of light–matter interaction.

We are investigating novel effects and applications using positrons and structured surfaces.

Metasurfaces are ultra-thin nanostructured materials that can shape and control light in extraordinary ways, but to be practical they must be tunable rather than fixed. This project develops liquid crystal–integrated metasurfaces to create reconfigurable flat optical devices for dynamic focusing, beam steering, and advanced sensing.

This project will pioneer compact, low-loss terahertz polarisation optics—polarisers, waveplates, and circular polarisers—by harnessing artificial birefringence in metamaterials to overcome the limitations of natural crystals.
