Resonance expansion of quadratic quantities with regularized quasinormal modes
Fridtjof Betz, Felix Binkowski, Martin Hammerschmidt +2
Resonance expansions are an intuitive approach to capture the interaction of an optical resonator with light. Here, we present a quasinormal mode expansion approach for quadratic o…

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…
