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…

Time-Domain Bound States in the Continuum
Oded Schiller, Yonatan Plotnik, Ohad Segal +2
We present the concept of time-domain bound states in continuum. We show that a rapid judiciously-designed temporal modulation of the refractive index in a spatially homogenous med…
