About Time: Observation of Time-Reflection at Optical Frequencies
Ohad Segal, Noa Konforty, Oded Schiller +9
Time-reflection occurs when a wave is propagating in a medium undergoing a large and abrupt change in its properties: the original wave splits into a time-refracted wave and a time…
Experimental Observation of Time-Domain Bound States in The Continuum
Zahra Manzoor, Oded Schiller, Yonatan Plotnik +2
Bound states in the continuum (BICs) are spatially localized eigenmodes that remain perfectly confined even though their energies reside within a continuum of radiating modes. BICs…
Sub-cycle time-refraction at optical frequencies
Ohad Segal, Noa Konforty, Oded Schiller +4
Large and abrupt variations in the electromagnetic properties of materials lead to dramatic effects: even a single step-like change in the refractive index induces striking phenome…
Negative Index Makes a Perfect Time-Domain Lens, Generating Slow Playback of Ultrafast Events
Oded Schiller, Yonatan Plotnik, Guy Bartal +1
We explore the effects of incorporating negative index materials into the physics of time-varying media and find that changing the refractive index from positive to negative create…
2D Topological Edge States in Periodic Space-Time Interfaces
Ohad Segal, Yonatan Plotnik, Eran Lustig +4
Topological edge states in systems of two (or more) dimensions offer scattering-free transport, exhibiting robustness to inhomogeneities and disorder. In a different domain, time-m…
Long lived surface plasmons on the interface of a metal and a photonic time-crystal
Lior Bar-Hillel, Yonatan Plotnik, Ohad Segal +1
We predict the existence of surface plasmons polaritons at the interface between a metal and a periodically modulated dielectric medium, and find an unusual multi-branched dispersi…
