Pole-Expansion of the T-Matrix Based on a Matrix-Valued AAA-Algorithm

Jan David Fischbach, Fridtjof Betz, Lukas Rebholz +6

The transition matrix (T-matrix) is a complete description of an object's linear scattering response. As such, it has found wide adoption for the theoretical and computational desc…

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…

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…

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…

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…
