Biomolecules and nanostructures

The Optical Sciences group studies the interaction of light and matter at the nanoscale. We do this by exploring ways to shape light and its environment. It's what we call active and passive control. Our current focus is on the interaction of light with biomolecules and nanostructures. We are part of Twente University's Department of Science and Technology and member of the MESA+ institute.
We participate in the EU-COST actions MP1102: Coherent Raman microscopy (MicroCor) and CM1202: Supramolecular photocatalytic water splitting (PERSPECT-H2O)

 

Quantum Photonics in Random cavities

  • This is a project of the Mesa+ Strategic Research Orientation Applied NanoPhotonics which is lead by Dr. Pepijn Pinkse.

    "We want to apply near-field scanning optical microscopy (NSOM) techniques to study light emission of quantum dots interacting with random cavities"" in photonic-crystal slab waveguides. In the waveguides, made by a team from the Danish Technical University (DTU), light scatters randomly from structural disorder stopping its propagation by interference, a phenomenon called Anderson localization. Mapping out the quantum dots and the localized light with the ultimate resolution of an NSOM allows us to extract a wealth of novel data such as the distribution of localization lengths of the modes and their spatial and spectral distribution. Since the light-emitting properties of the quantum dots are best at low temperatures, cryogenic experiments are planned."
