    • Far-field control of nanoscale hotspots by near-field interference 

      Singh, Anshuman; Hugall, James T.; Calbris, Gaëtan; Hulst, Niek F. van (ACS, 2020-07-31)
      Article
      Open Access
      Optical nanoantennas coherently scatter incident optical radiation, creating a localized electromagnetic near-field imprinted with subwavelength phase distribution, rapidly changing in space. The nanostructuring of phase ...
    • 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. ...
    • Optical nanoantennas as cavities : nanoscale control of couplings strength and single photon emission 

      Singh, Anshuman (Universitat Politècnica de Catalunya, 2017-11-11)
      Doctoral thesis
      Open Access
      Optical nanoantennas confine light on the nanoscale, enabling strong light-matter interactions with potential for ultra-compact optical devices. Apart from the direct applications in optical nanoscopy and sensing, nanoantennas ...
    • Plasmonic Nanocavity Coupling 

      Hugall, James T.; Singh, Anshuman; Hulst, Niek F. van (ACS, 2018-01-08)
      Article
      Open Access
      The large losses of plasmonic nanocavities, orders of magnitude beyond those of photonic dielectric cavities, places them, perhaps surprisingly, as exceptional enhancers of single emitter light‐matter interactions. The ...
