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…
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…
Fabrication uncertainty guided design optimization of a photonic crystal cavity by using Gaussian processes
Matthias Plock, Felix Binkowski, Lin Zschiedrich +2
We present a fabrication uncertainty aware and robust design optimization approach that can be used to obtain robust design estimates for nonlinear, nonconvex, and expensive model…
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…
