We demonstrate that spatiotemporal discrete solitons are possible in nonlinear photonic crystal structures. Analysis indicates that these states can propagate undistorted along a series of coupledâ€¦ (More)

We report the first experimental observation of discrete solitons in an array of optically induced waveguides. The waveguide lattice is induced in real time by illuminating a photorefractive crystalâ€¦ (More)

We demonstrate that optical discrete solitons are possible in appropriately oriented biased photorefractive crystals. This can be accomplished in optically induced periodic waveguide lattices thatâ€¦ (More)

Discrete solitons in nonlinear zigzag optical waveguide arrays with tailored diffraction properties.

We show that the discrete diffraction properties of a nonlinear optical zigzag waveguide array can be significantly modified, by exploiting the topological arrangement of the lattice itself. Thisâ€¦ (More)

We demonstrate that light propagating in an appropriately designed lattice can exhibit dynamics akin to that expected from massless relativistic particles as governed by the one-dimensional Diracâ€¦ (More)

We demonstrate, for the first time, that photonic lattices support a new type of laser filaments, called lattice filaments (LF). The LF attributes (length, width, and intensity) can be tailored byâ€¦ (More)

We developed an efficient hybrid mode expansion method to study the maximum tunneling current as a function of the external magnetic field for a 2D large area lateral window junction. We consider theâ€¦ (More)

We introduce a new class of propagation invariant spatiotemporal wavepackets. The evolution of these light orbitals is here considered theoretically. Archimedean photonic lattices can be generatedâ€¦ (More)

We demonstrate optical beam auto-focusing without the need of a focusing lens or nonlinearity. Radial Airy beams with inward and outward accelerations are used and an abrupt transition between Airyâ€¦ (More)

A circular array of optical waveguides collectively coupled with a central core is investigated. Both linear and nonlinear coupling as well as energy transfer within the array elements and with theâ€¦ (More)
