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. 

Metasurface can the generation and manipulation of polarization-entangled photon pairs at the nanoscale.

The goal of the project is to understand new physical phenomena arising from quantum and nonlinear optical integration. In the future this research may open doors to new types of computers and simulators with information capacity exceeding the number of elementary particles in the entire universe.

This project investigates novel 2D materials for compact quantum photonic devices. Students will fabricate and characterize material thin films, study their nonlinear optical properties, and use experimental data to simulate metasurfaces for entangled-photon generation, gaining hands-on experience in nanofabrication, optical characterization, nonlinear optics, and quantum photonics.

This project aims for developing polarization optical devices based on all-dielectric metasurfaces. As no bulky optical elements and moving parts are required, these devices are compact, stable, and can operate in a single-shot mode with high time resolution. Potential applications include sensitive biological imaging and quantum state manipulation and tomography.
