On the time evolution at a fluctuating exceptional point
Christian Wolff, Christos Tserkezis, N. Asger Mortensen
We theoretically evaluate the impact of drift-free noise on the dynamics of -symmetric non-Hermitian systems with an exceptional point, which have recently been propo…
Direct characterization of near-field coupling in gap plasmon-based metasurfaces
Rucha Deshpande, Vladimir A. Zenin, Fei Ding +2
Metasurfaces based on gap surface-plasmon resonators allow one to arbitrarily control the phase, amplitude and polarization of reflected light with high efficiency. However, the pe…
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…
Modal expansions in periodic photonic systems with material loss and dispersion
Christian Wolff, Kurt Busch, N. Asger Mortensen
We study bandstructure properties of periodic optical systems composed of lossy and intrinsically dispersive materials. To this end, we develop an analytical framework based on adj…
