Research

My group works on fundamental research in nanophotonics and nanoelectronics and its applications for optoelectronic and quantum photonics devices. Applications target novel quantum light sources, nanolasers, tunable light detectors, flexible solar cells, as well as on-chip platforms for optical quantum computing. A strong focus is to control the light-matter interaction utilizing either dielectric or plasmonic nanocavities and to explore the photophysical properties of excitons and their interaction with phonons and plasmons at the nanoscale. Our targeted materials are carbon nanotubes,
monolayer transition metal dichalcogenides (TMDCs) and hexagonal Boron Nitride color centers. We also have new efforts in growth and nanofabrication of Lithium Niobate (LiNbO3) for on-chip quantum memory applications.
