Levitodynamics
Vacuum trapped nanoparticles exhibit very high quality factors (Q>107), which makes them attractive for ultrasensitive detection and metrology. We optically trap single nanoparticles in high vacuum and cool their center-of-mass motion to low temperatures by active or dynamic back-action. More information about levitodynamics...
2D Optoelectronics
We develop and study optoelectronic devices made of two-dimensional materials for on-chip photonics and co-integration with electronic circuitry. We aim to understand the device physics and push operating parameters beyond current limits. More information on 2D optoelectronics...
Optical antennas
Optical antennas are devices that enhance the local light-matter interaction. We use optical antennas to improve the quantum efficiency of single quantum emitters and to engineer their emission properties. More information on optical antennas...
Nearfield Optics
Optical near-fields are characterized by non-propagating evanescent fields. We study them for high-resolution microscopy and spectroscopy, for sensing, and for optical manipulation. More information on nearfield optics...
Nonlinear Plasmonics
Metals and their interfaces exhibit high nonlinear optical coefficients. We study their properties in regards to on-chip wavelength-conversion, optical modulation, and single-photon switching. More information on nonlinear plasmonics...
Nanocarbon Photonics
Due to their unique bandstructures carbon nanotubes and graphene exhibit very attractive optoelectronic properties. We study the influence of local defects and dopants in such materials. More information on nanocarbon photonics...
