Spectral Diffusion Mitigation with a Laser Pulse Sequence
Kilian Unterguggenberger, Alok Gokhale, Aleksei Tsarapkin +6
The optical spectrum of a quantum system is jointly determined by the properties of the emitter and the driving field. All-optical spectral control can hence be a promising method…
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…
Direct electron beam writing of silver using a -diketonate precursor: first insights
Katja Höflich, Krzysztof Mackosz, Chinmai S. Jureddy +2
Direct electron beam writing is a powerful tool for fabricating complex nanostructures in a single step. The electron beam locally cleaves the molecules of an adsorbed gaseous prec…
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…
Optical probing of phononic properties of a tin-vacancy color center in diamond
Cem Güney Torun, Joseph H. D. Munns, Franziska Marie Herrmann +12
The coherence characteristics of a tin-vacancy color center (SnV) in diamond are investigated through optical means, including linewidth broadening effects and coherent population…
