Our infrastructure

The Resonant Nanophotonics group develops state of the art methods in nanoscopy, fluorescence microscopy and single molecule microscopy, scatterometry, near-field manipulation and nanofabrication. A non-exhaustive list of our set ups:

  • Supercontinuum scatterometry (NKT SuperK Extreme, any wavelength from 450 to 2000 nm), transmission, reflection and dark field
  • Back-focal plane or `Fourier’ microscopy: mapping of single nano-antenna radiation patterns and differential scattering cross sections with sub-degree resolution, over large angular ranges (NA=1.4) from visible to NIR.  For scattering and (single molecule) fluorescence
  • Single-molecule microscopy, including spectroscopy, time-correlated single photon counting for fluorescence lifetime and g(2)-antibunching, and fluorescence correlation spectroscopy, applicable to room-temperature emitters in the visible
  • Montana cryostat for low-temperature (down to 3K) single emitter microscopy
  • Scanning near-field microscopy with homebuilt tuning-fork shear-force feedback, synchronized with fluorescence spectral imaging and time-correlated single-photon counting
  • Fourier-space fluorescence microscopy to study plasmon lasers. Integrated with spatial-light modulation (SLM) to control amplitude and phase profiles of pump beams
  • Twin-OPA system (LightConversion Orpheus F) delivering down to 30 fs pulses from 650 to 900 nm, and from 1100 to 2000 nm, feeding into ultrafast pulse interferometry, and designed for pump-probe microscopy experiments
  • Narrowband cw spectroscopy near 780 nm for interrogating high Q cavity systems, integrated with a set up to measure through integrated waveguides, approached tapered fibers, or through near- and far-field addressing in a microscope
  • We make heavy use of the AMOLF NanoLab Amsterdam cleanroom operated by AMOLF for top-down sample fab by e-beam lithography and focused ion beam milling.
