    • Single molecules in a dielectric nanoguide
  • The research of our group aims to advance experimental and theoretical mastery of light-matter interaction at the nanometer scale and to achieve the same degree of control and finesse that is known from the gas-phase quantum optics in the condensed phase. To do this, we combine concepts from quantum optics, laser spectroscopy, cryogenics, optical imaging, scanning probe technology and nanofluidics. In this endeavour, we have addressed a wide spectrum of scientific questions, ranging from quantum optics to biophysics. For more information, please consult our research website and our list of publications.

Biexciton emission strongly enhanced by plasmonic nano-cone

Semiconductor quantum dots (Q-dots) are desirable in many applications because they can emit multiple photons for each excitation pulse via the generation of multiple excitons. In practice, however, multi excitonic emissions are...[more]


A single molecule as a high-fidelity photon-gun for producing intensity-squeezed light

Generation of light with intensity fluctuations below the shot-noise limit has been one of the most important challenges in quantum optics. An elegant approach was proposed in the 1980s: through excitation of a two-level atom, a...[more]


Cryogenic optical localization provides 3D protein structure data with Angstrom resolution

Starting with efforts in scanning nearfield optical microscopy in the 1980s, many laboratories around the world have contributed to pushing the resolution of optical imaging beyond the Abbe limit [1]. A particularly fruitful...[more]
