Photonic Floquet Topological Insulators
Mikael C. Rechtsman, Julia M. Zeuner, Yonatan Plotnik +4
The topological insulator is a fundamentally new phase of matter, with the striking property that the conduction of electrons occurs only on its surface, not within the bulk, and t…
Topological creation and destruction of edge states in photonic graphene
Mikael C. Rechtsman, Yonatan Plotnik, Julia M. Zeuner +2
We demonstrate theoretically and experimentally a topological transition of classical light in "photonic graphene": an array of waveguides arranged in the honeycomb geometry. As th…
Observation of novel edge states in photonic graphene
Mikael C. Rechtsman, Yonatan Plotnik, Daohong Song +8
The intriguing properties of graphene, a two-dimensional material composed of a honeycomb lattice of carbon atoms, have attracted a great deal of interest in recent years. Specific…
Strain-induced pseudomagnetic field and Landau levels in photonic structures
Mikael C. Rechtsman, Julia M. Zeuner, Andreas Tünnermann +3
Magnetic effects at optical frequencies are notoriously weak. This is evidenced by the fact that the magnetic permeability of nearly all materials is unity in the optical frequency…
Sub-Wavelength Nonlinear Accelerating Beams
Ido Kaminer, Mordechai Segev
We show that optical nonlinearities allow sub-wavelength beams to propagate in circular trajectories without being attenuated in spite of their partially evanescent spectrum. Such…
Designing and using prior data in Ankylography: Recovering a 3D object from a single diffraction intensity pattern
Eliyahu Osherovich, Oren Cohen, Yonina C. Eldar +1
We present a novel method for Ankylography: three-dimensional structure reconstruction from a single shot diffraction intensity pattern. Our approach allows reconstruction of objec…
