  • Plasmonic Nanopore for Electrical Profiling of Optical Intensity Landscapes
  • 2013
  • In: Nano letters (Print). - : American Chemical Society. - 1530-6984 .- 1530-6992. ; 13:3, s. 1029-1033
  • Journal article (peer-reviewed)abstract
    • We present a novel method for sensitive mapping of optical intensity distributions at subdiffraction-limited resolution. This is achieved with a novel device, a plasmonic nanopore, which combines a plasmonic bowtie nanoantenna with a 10 nm-in-diameter solid-state nanopore. Variations in the local optical intensity modulate the plasmonic heating, which we measure electrically through changes in the ionic conductance of the nanopore. We demonstrate the method by profiling the focal volume of a 10 mW laser beam that is tightly focused by a high-numerical-aperture microscope objective. The results show a complex three-dimensional intensity distribution that closely matches predictions obtained by theoretical calculations of the optical system. In addition to laser profiling, the ionic conductance of a nanopore is also shown to provide quantitative estimates of the temperature in the proximity of single plasmonic nanostructures.

  • Periodic Modulations of Optical Tweezers Near Solid-State Membranes
  • 2013
  • In: Small. - : Wiley-VCH Verlag. - 1613-6810 .- 1613-6829. ; 9:5, s. 679-684
  • Journal article (peer-reviewed)abstract
    • Optical tweezers operated near solid-state membranes show unexplained periodic modulations in the optical trap position. An experimental study of the oscillations is presented, as well as optical simulations based on the finite-difference time-domain method, providing insight into the underlying interference phenomenon. This work provides a complete description as well as a solution to the enduring problem of modulations in optical traps near solid-state membranes.
