Resonance modes in microstructured photonic waveguides: Efficient and accurate computation based on AAA rational approximation
Felix Binkowski, Fridtjof Betz, Martin Hammerschmidt +2
We present a framework for the efficient and accurate computation of resonance modes in photonic waveguides. The framework is based on AAA rational approximation with the applicati…
Computing eigenfrequency sensitivities near exceptional points
Felix Binkowski, Julius Kullig, Fridtjof Betz +4
Exceptional points are spectral degeneracies of non-Hermitian systems where both eigenfrequencies and eigenmodes coalesce. The eigenfrequency sensitivities near an exceptional poin…
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…
