Three-dimensional photonic topological insulator induced by lattice dislocations
Eran Lustig, Lukas J. Maczewsky, Julius Beck +6
The hallmark of topological insulators is the scatter-free propagation of waves in topologically protected edge channels. This transport is strictly chiral on the outer edge of the…
Amplified Emission by Atoms and Lasing in Photonic Time Crystals
Mark Lyubarov, Yaakov Lumer, Alex Dikopoltsev +3
Photonic Time Crystals (PTCs) - dielectric media with their refractive index modulated periodically in time, offer new opportunities in photonics arising from time reflections and…
Light Emission by Free Electrons in Photonic Time-Crystals
Alex Dikopoltsev, Yonatan Sharabi, Mark Lyubarov +5
Photonic time-crystals (PTCs) are spatially-homogeneous media whose electromagnetic (EM) susceptibility varies periodically in time, causing temporal reflections and refractions fo…
Photonic Floquet topological insulators in a fractal lattice
Zhaoju Yang, Eran Lustig, Yaakov Lumer +1
We present Floquet fractal topological insulators: photonic topological insulators in a fractal-dimensional lattice consisting of helical waveguides. The helical modulation induces…
Generalized Laws of Refraction and Reflection at Interfaces between Different Photonic Artificial Gauge Fields
Moshe-Ishay Cohen, Christina Jörg, Yaakov Lumer +5
Artificial gauge fields enable extending the control over dynamics of uncharged particles, by engineering the potential landscape such that the particles behave as if effective ext…
Mode-Locked Topological Insulator Laser Utilizing Synthetic Dimensions
Zhaoju Yang, Eran Lustig, Gal Harari +4
We propose a system that exploits the fundamental features of topological photonics and synthetic dimensions to force many semiconductor laser resonators to synchronize, mutually l…
