      Optical nanoantennas are well-known for the confinement of light into nanoscale hot spots, suitable for emission enhancement and sensing applications. Here, we show how control of the antenna dimensions allows tuning ...
    • Enhancing Magnetic Light Emission with All-Dielectric Optical Nanoantennas 

      Sanz-Paz, Maria; Ernandes, Cyrine; Esparza, Juan Uriel; Burr, Geoffrey W.; van Hulst, Niek F.; Maître, Agnès; Aigouy, Lionel; Gacoin, Thierry; Bonod, Nicolas; Garcia-Parajo, Maria F.; Bidault, Sébastien; Mivelle, Mathieu (ACS, 2018-04-27)
      Article
      Open Access
      Electric and magnetic optical fields carry the same amount of energy. Nevertheless, the efficiency with which matter interacts with electric optical fields is commonly accepted to be at least 4 orders of magnitude higher ...
    • Nanoscale mapping and control of antenna-coupling strength for bright single photon sources 

      Singh, Anshuman; Roque, Pablo M. de; Calbris, Gaëtan; Hugall, James T.; van Hulst, Niek F. (ACS, 2017-03-23)
      Article
      Open Access
      Cavity QED is the art of enhancing light-matter interaction of photon emitters in cavities, with opportunities for sensing, quantum information and energy capture technologies. To boost emitter-cavity interaction, i.e. ...
    • Room Temperature Excitation-Emission Spectra of Single LH2 Complexes Show Remarkably Little Variation 

      Gellings, Esther; Cogdell, Richard J.; van Hulst, Niek F. (ACS, 2020-03-06)
      Article
      Restricted access - publisher's policy
      Excitation spectroscopy gives direct insight into the excited state manifold, energy transfer, transient intermediates, vibrations, and so on. Unfortunately, excitation spectroscopy of single molecules under ambient ...
    • Ultrafast meets ultrasmall: controlling nanoantennas and molecules 

      Piatkowski, Lukasz; Accanto, Nicolò; van Hulst, Niek F. (ACS, 2016-04-25)
      Article
      Open Access
      We present a review on the advances of pulse control and ultrafast coherent excitation of both plasmonic nanoantennas and individual molecular systems, primarily based on the achievements in our group. Essential concepts ...
