In the NanoOptics group we focus on the behavior of light fields at the nanoscale with the aim to mold the flow of light with nanophotonic structures. As the typical length scale of these structures is smaller than the optical wavelength, light tends to exhibit counter-intuitive behavior and we can induce phenomena that do not occur in nature: slow light, rogue waves, superchirality and control of spontaneous emission. Our group is curiosity driven but not blind for potential application, which range from a faster and more efficient internet to enhanced (bio-)sensing. Unique is our ability to visualize light flows inside nanophotonic structures in time and space.
