Our research group explores nonlinear metasurfaces to achieve unprecedented control over light at the nanoscale, focusing on applications in quantum optics. By leveraging nanoscale spontaneous parametric down conversion (SPDC) and enhanced harmonic generation, we develop compact devices that enable efficient quantum light generation and frequency conversion. These advancements pave the way for on-chip integration in future quantum technologies.
