Biomolecules and nanostructures

The Optical Sciences group studies the interaction of light and matter. Our current focus is on detection and sensing/imaging with an emphasis on the development of integrated photonics. We are part of Twente University's Department of Science and Technology and member of the MESA+ institute.

 

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."
