Resonant states reveal strong light-matter coupling in nanophotonic cavities

Jan David Fischbach, Sergei Gladyshev, Adrià Canós Valero +3

Photonic resonances enable control over light-matter interactions, but many key phenomena only emerge in the strong-coupling regime where light and matter excitations fully hybridi…

Gradient-based optimization of scatterer arrangements based on the T-matrix method

Nigar Asadova, Jan David Fischbach, Renaud Vallée +6

The demand for inverse design is increasing as the ability to fabricate sub-10 nm features expands the design space by orders of magnitude. Efficient inverse design benefits from d…
