  NAM Christmas dinner

  This year, the traditional Christmas dinner had a nice and warm feeling: we enjoyed a mouthwatering couscous, while it was a freezing cold December night outside!

  Fano resonances: retrieving the underlying modal structure

  In plasmonic systems, Fano resonance originate from the interaction between a bright and a dark mode. Using our recently developed ab-initio formalism, we demonstrate that the underlying modal structure can be easily retrieved for a broad variety of experimental plasmonic systems.

  Fano resonances: relation between near-field and far-field

  In a recent publication we clarify the link between the near-field distribution and the far-field response of plasmonic structures that exhibit Fano resonances. The second publication analyzes in detail a broad variety of Fano resonant exprimental systems and shows how the ab-initio theory we have developped can be used to retrieve the underlying modal structure.

  Detection limit of plasmonic antennas

  Having previously demonstrated that plasmonic antennas can be used for trapping at the nanoscale, we have now investigated the detection limit of such an antenna: particles as small as 5nm can be detected this way!

  Bending plasmons around the corner

  A detailed analysis of the integration of plasmonic waveguides in realistic photonic circuits is performed and design rules are established for the coupling between conventional photonic and plasmonic waveguides.

  Oxygen sensing using a strongly coupled bio-plasmonic system

  We demonstrate that using the coupling between plasmonic resonances and analyte can dramatically increase the sensitivity of a biosensor. This new scheme is applied to measure the oxygen content of hemoglobin.
