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…
