Our laboratory explores quantum dynamics in nanostructures and small molecules on time scales ranging from femto- to nanoseconds. Our goal is to study quantum decoherence at the nano- and mesoscale, to clarify the role of quantum effects in molecular photophysics and photochemistry, and to explore new nanomaterials for emerging quantum technologies.
Exploring quantized structures based on emerging semiconductors in both photonics and electronics. This covers a broad research area starting from fundamental studies around light-matter interaction in microcavities and nanostructures,
Photonic crystals are defined by a periodic modulation of the dielectric function on the wavelength scale in electromagnetic structures. They exhibit many original properties such as enhancement or inhibition of spontaneous emission and numerous applications in applied science like nanophotonics and integrated optics due to their ability to control both light propagation and localization at the wavelength scale. We are mainly working on bi-dimensional structures etching on III-V or Si planar waveguides. We focus mainly on light propagation in the slow light regime and disorder effects, high-Q cavities, hollow photonic crystals structures with a large field overlap with the environment and extension to visible range material systems.
