Extreme Ultrafast Dynamics of the Refractive Index in Transparent Conductive Oxides: Theory and Experiment
Noa Konforty, Graham G. Brown, Ohad Segal +5
Recent experiments in transparent conductive oxides (TCOs) have revealed light-induced order-unity variations in the refractive index occurring at extreme time scales, as short as…
Acceleration of Free Electrons by Photonic Time-Crystals
Lior Bar-Hillel, Alexey Gorlach, Ido Kaminer +1
We study the quantum interaction between free electrons and photons in a time-varying media, and find that periodic modulation exponentially amplifies electron-photon coupling with…
Demonstration of Broadband Non-Resonant Time-Crystal Amplification in Microwaves
Thomas R. Jones, Ludmila J. Prokopeva, Alexander V. Kildishev +2
We report an optically modulated experimental realization of a photonic time crystal (PTC) in the microwave regime, demonstrating for the first time that the PTC exponential growth…
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…
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…
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…
