Amorphous Photonic Lattices: Band Gaps, Effective Mass and Suppressed Transport
Mikael Rechtsman, Alexander Szameit, Felix Dreisow +4
We present, theoretically and experimentally, amorphous photonic lattices exhibiting a band-gap yet completely lacking Bragg diffraction: 2D waveguides distributed randomly accordi…
Far-Field Microscopy of Sparse Subwavelength Objects
A. Szameit, Y. Shechtman, H. Dana +9
We present the experimental reconstruction of sub-wavelength features from the far-field of sparse optical objects. We show that it is sufficient to know that the object is sparse,…
Breakdown of Dirac Dynamics in Honeycomb Lattices due to Nonlinear Interactions
Omri Bahat-Treidel, Or Peleg, Hrvoje Buljan +1
We study the dynamics of coherent waves in nonlinear honeycomb lattices and show that nonlinearity breaks down the Dirac dynamics. As an example, we demonstrate that even a weak no…
