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…
Second Harmonic Generation and Nonlinear Frequency Conversion in Photonic Time-Crystals
Noa Konforty, Moshe-Ishay Cohen, Ohad Segal +2
We study the nonlinear process of second harmonic generation in photonic time-crystals, materials with refractive index that varies abruptly and periodically in time, and obtain th…
