High Purcell enhancement in all-TMDC nanobeam resonator designs with active monolayers for nanolasers
Felix Binkowski, Aris Koulas-Simos, Fridtjof Betz +9
We propose a nanobeam resonator incorporating an active monolayer, designed to achieve a high Purcell enhancement. The resonator is fully composed of transition-metal-dichalcogenid…
Uncovering hidden resonances in non-Hermitian systems with scattering thresholds
Fridtjof Betz, Felix Binkowski, Jan David Fischbach +5
The points where diffraction orders emerge or vanish in the propagating spectrum of periodic non-Hermitian systems are referred to as scattering thresholds. Close to these branch p…
Modeling luminescent coupling in multi-junction solar cells: Perovskite Silicon tandem case study
Phillip Manley, Martin Hammerschmidt, Lin Zschiedrich +3
Luminescent coupling is a characteristic of multi-junction solar cells which has often been neglected in models of their performance. The effect describes the absorption of light e…
Efficient rational approximation of optical response functions with the AAA algorithm
Fridtjof Betz, Martin Hammerschmidt, Lin Zschiedrich +2
We introduce a theoretical framework for the rational approximation of optical response functions in resonant photonic systems. The framework is based on the AAA algorithm and furt…
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…
Forward simulation of coherent beams on grating structures for coherent scatterometry
Martin Hammerschmidt, Lin Zschiedrich, Lauryna Siaudinyté +3
Modelling the scattering of focused, coherent light by nano-scale structures is oftentimes used to reconstruct or infer geometrical or material properties of structures under inves…
