Anisotropic Second Harmonic Generation From Monocrystalline Gold Flakes
Sergejs Boroviks, Torgom Yezekyan, Álvaro Rodríguez Echarri +5
Noble metals with well-defined crystallographic orientation constitute an appealing class of materials for controlling light-matter interactions on the nanoscale. Nonlinear optical…
Unidirectional single-photon emission from germanium-vacancy zero-phonon lines: Deterministic emitter-waveguide interfacing at plasmonic hot spots
Hamidreza Siampour, Ou Wang, Vladimir A. Zenin +10
Striving for nanometer-sized solid-state single-photon sources, we investigate atom-like quantum emitters based on single germanium vacancy (GeV) centers isolated in crystalline na…
Interference in edge-scattering from monocrystalline gold flakes
Sergejs Boroviks, Christian Wolff, Jes Linnet +6
We observe strongly dissimilar scattering from two types of edges in hexagonal quasi-monocrystalline gold flakes with thicknesses around 1 micron. We identify as the origin the int…
Laser writing of bright colours on near-percolation plasmonic reflector arrays
Alexander S. Roberts, Sergey M. Novikov, Yuanqing Yang +5
Colouration by surface nanostructuring has attracted a great deal of attention by the virtue of making use of environment-friendly recyclable materials and generating non-bleaching…
