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…
A framework to compute resonances arising from multiple scattering
Jan David Fischbach, Fridtjof Betz, Nigar Asadova +8
Numerous natural and technological phenomena are governed by resonances. In nanophotonics, resonances often result from the interaction of several optical elements. Controlling the…
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…
Applying a Riesz-projection-based contour integral eigenvalue solver to compute resonance modes of a VCSEL
Lilli Kuen, Fridtjof Betz, Felix Binkowski +6
We investigate the calculation of resonance modes of a VCSEL with a Riesz projection eigenvalue solver. The eigenvalue solver is based on the principle of contour integration where…
Computation of eigenfrequency sensitivities using Riesz projections for efficient optimization of nanophotonic resonators
Felix Binkowski, Fridtjof Betz, Martin Hammerschmidt +3
Resonances are omnipresent in physics and essential for the description of wave phenomena. We present an approach for computing eigenfrequency sensitivities of resonances. The theo…
Quasinormal mode solvers for resonators with dispersive materials
P. Lalanne, W. Yan, A. Gras +16
Optical resonators are widely used in modern photonics. Their spectral response and temporal dynamics are fundamentally driven by their natural resonances, the so-called quasinorma…
A Riesz-projection-based method for nonlinear eigenvalue problems
Felix Binkowski, Lin Zschiedrich, Sven Burger
We propose an algorithm for general nonlinear eigenvalue problems to compute physically relevant eigenvalues within a chosen contour. Eigenvalue information is explored by contour…
