Project description

Nanophotonics has revolutionized optics by controlling light propagation on length scales far below the optical diffraction limit, enabling breakthrough applications in energy harvesting, beam shaping, and few-molecule biodetection. However, current approaches still face limitations due to the intrinsic losses with of commonly used metals. In this project, we will investigate and develop a new class of spectrally- selective metasurfaces with ultrasharp resonances composed of all-dielectric materials [1] and apply them for advanced biospectroscopy and resonant coupling experiments. This combination of molecular spectroscopy and nanophotonic engineering, aided by machine learning [2] for design and analysis, will provide fundamental insights into the behavior of complex biochemical and cellular systems, with a broad impact from physics to medicine.
