Analysis of artificial opals by scanning near field optical microscopy
(American Institute of Physics, 2011-04)
Herein we present a detailed analysis of the optical response of artificial opal films realized employing a near-field scanning optical microscope in collection and transmission modes. Near-field patterns measured at the ...
Experimental verification of the spectral shift between near- and far-field peak intensities of plasmonic infrared nanoantennas
(American Physical Society, 2013-03)
Theory predicts a distinct spectral shift between the near- and far-field optical response of plasmonic antennas. Here we combine near-field optical microscopy and far-field spectroscopy of individual infrared-resonant ...

Harmonic demodulation and minimum enhancement factors in field-enhanced near-field optical microscopy
(Wiley Blackwell Publishing, Inc, 2015-01)
Field enhanced scanning optical microscopy (FESOM) relies on the design and fabrication of plasmonic probes which had to provide optical and chemical contrast at the nanoscale. In order to do so, the scattering containing ...

Visualizing the near-field coupling and interference of bonding and anti-bonding modes in infrared dimer nanoantennas
(Optical Society Of America, 2013-01)
We directly visualize and identify the capacitive coupling of infrared dimer antennas in the near field by employing scattering-type scanning near-field optical microscopy (s-SNOM). The coupling is identified by (i) resolving ...
