Double tips for in-plane polarized near-field microscopy and spectroscopy
Patryk Kusch, Jose Pareja Arcos, Aleksei Tsarapkin +4
Near-field optical microscopy and spectroscopy provide high-resolution imaging below the diffraction limit, crucial in physics, chemistry, and biology for studying molecules, nanop…
Double helical plasmonic antennas
Aleksei Tsarapkin, Luka Zurak, Krzysztof Maćkosz +5
Plasmonic double helical antennas are a means to funnel circularly polarized light down to the nanoscale. Here, an existing design tool for single helices is extended to the case o…
Chiral and directional optical emission from a dipole source coupled to a helical plasmonic antenna
Lilli Kuen, Lorenz Löffler, Aleksei Tsarapkin +4
Plasmonic antennas with helical geometry are capable transducers between linearly polarized dipole emission and purely circular polarized far-fields. Besides large Purcell enhancem…
