ABOUT

The group focuses on the study of the optical properties of nanostructured materials and surfaces as well as the design of integrated photonic devices. Our aim is to understand the behavior of light in complex, often periodic environments. In particular we are interested in optical properties of metallic and dielectric nanostructured surfaces also called metasurfaces and their ability to arbitrarily control the wavefront and polarization of light. Such surfaces can be used as passive elements like submicron thick lenses and polarization controllers, but also in active devices, since they influence light emission, photoluminescence, Raman, and lasing, and absorption with applications in photovoltaics.

Moreover we consider the interaction of light with elastic waves or spin waves, in order to design devices that can efficiently control light propagation, and develop hybrid information processing platforms by facilitating the coupling between different kinds of waves that will enable efficient photon-phonon or photon-magnon transducers. We develop theoretical tools to model the light propagation in periodic media using multiple scattering theory. Together with the theoretical study we design and fabricate prototype devices and surfaces and characterize photonic surfaces and integrated photonic devices.
