  • Effect of stray fields on Rydberg states in hollow-core PCF probed by higher-order modes. 

    Epple, G; Joly, NY; Euser, Tijmen; St J Russell, P; Löw, R (Optical Society of America, 2017-09)
    The spectroscopy of atomic gases confined in hollow-core photonic crystal fiber (HC-PCF) provides optimal atom-light coupling beyond the diffraction limit, which is desirable for various applications such as sensing, ...
  • Plasmonic tunnel junctions for single-molecule redox chemistry 

    de Nijs, Bart; Benz, F; Barrow, SJ; Sigle, DO; Chikkaraddy, Rohit; Palma, A; Carnegie, Cloudy et al.
    Nanoparticles attached just above a flat metallic surface can trap optical fields in the nanoscale gap. This enables local spectroscopy of a few molecules within each coupled plasmonic hotspot, with near thousand-fold ...
  • Molecules in the mirror: how SERS backgrounds arise from the quantum method of images 

    Baumberg, Jeremy; Barnett, Stephen; Harris, Nadine (RSC Publishing, 2014-02-20)
    The Raman coupling of light to molecular vibrations is strongly modified when they are placed near a plasmonic metal surface, with the appearance of a strong broad continuum background in addition to the normal surface-enhanced ...
