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…
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…
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…
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…
