Bound states in the continuum in multilayered time-varying metasurfaces
Puneet Garg, Michael Plum, Carsten Rockstuhl
Time-varying metamaterials involve a rapid temporal modulation of the permittivity, often at frequencies comparable to the oscillation frequency of light. However, pronounced physi…
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…
Exceptional Points, Lasing, and Coherent Perfect Absorption in Floquet Scattering Systems
David Globosits, Puneet Garg, Jakob Hüpfl +4
Periodically time-varying media, known as photonic time crystals (PTCs), provide a promising platform for observing unconventional wave phenomena. We analyze the scattering of elec…
Uncovering hidden resonances in non-Hermitian systems with scattering thresholds
Fridtjof Betz, Felix Binkowski, Jan David Fischbach +5
The points where diffraction orders emerge or vanish in the propagating spectrum of periodic non-Hermitian systems are referred to as scattering thresholds. Close to these branch p…
Photonic time crystals assisted by quasi-bound states in the continuum
P. Garg, E. Almpanis, L. Zimmer +8
Photonic time crystals are a class of artificial materials that have only recently been explored. They are characterized by the ultrafast modulation of the material properties in t…
Inverse-designed dispersive time-varying nanostructures
Puneet Garg, Jan David Fischbach, Aristeidis G. Lamprianidis +5
Time-varying nanostructures allow us to control the spatial and temporal properties of light. The temporal modulation of the nanostructures constitutes an additional degree of free…
