Interaction of nematicons in a bias-free liquid crystal cell
Yana Izdebskaya, Vladlen Shvedov, Anton S. Desyatnikov +3
We study experimentally the propagation dynamics and interaction of spatial optical solitons in a bias-free cell filled with nematic liquid crystals. We reveal and measure long-ran…
Spin and orbital Hall effects for diffracting optical beams in gradient-index media
K. Y. Bliokh, A. S. Desyatnikov
We examine the evolution of paraxial beams carrying intrinsic spin and orbital angular momenta (AM) in gradient-index media. A parabolic-type equation is derived which describes th…
Optical Vortices during a Super-Resolution Process in a Metamaterial
G. D'Aguanno, N. Mattiucci, M. Bloemer +1
We show that a super-resolution process with 100% visibility is characterized by the formation of a point of phase singularity in free space outside the lens in the form of a saddl…
Photonic Bloch oscillations and Zener tunneling in two-dimensional optical lattices
Henrike Trompeter, Wieslaw Krolikowski, Dragomir N. Neshev +6
We report on the first experimental observation of photonic Bloch oscillations and Zener tunneling in two-dimensional periodic systems. We study the propagation of an optical beam…
Focusing and correlation properties of white-light optical vortices
Vladlen Shvedov, Wieslaw Krolikowski, Alexander Volyar +3
We generate double-charge white-light optical vortices by sending a circularly polarized partially incoherent light through an uniaxial crystal. We show that the generated polichro…
Nonlinear photonic lattices in anisotropic nonlocal self-focusing media
Anton S. Desyatnikov, Dragomir N. Neshev, Yuri S. Kivshar +5
We analyze theoretically and generate experimentally two-dimensional nonlinear periodic lattices in a photorefractive medium. We demonstrate that the light-induced periodically mod…
