Applied and Integrated Photonics

  • Compact optical tweezers system with MEMS steering optics and optomechanics for biomedical applications.
  • The use of photolithographic methods, wet and dry etching to produce optical elements, microfluidics and metasurfaces.
  • Microchip for optical trapping of micro-objects under low pressure.
  • Metaoptics structures for aberration-free imaging and spectroscopy systems.
  • Inspection by Scanning Probe Microscopy with emphasis on the surface topography of prepared nanostructures and films & coatings.
  • Determination of mechanical properties such as elastic modulus, hardness or film adhesion by nanoindentation measurements and scratch testing.
  • Microfluidic acoustic wave based sorting chips.
  • Arbitrary shaped optical gratings and micro-optical elements.
