چکیده

We generate higher-order azimuthally modulated Bessel optical lattices in photorefractive crystals by employing a phase-imprinting technique. We report on the experimental observation of self-trapping and nonlinear localization of light in such segmented lattices in the form of ring-shaped and single-site states. The experimental results agree well with numerical simulations accounting for an anisotropic and spatially nonlocal nonlinear response of photorefractive crystals.

Light localization in azimuthally modulated Bessel photonic lattices

We study the propagation and localization of light beams in azimuthally modulated Bessel photonic lattices induced optically in photorefractive crystals; such lattices resemble highly nonlinear micro-structured fibres. We report on the experimental observation of discrete diffraction, nonlinear localization, and subsequent formation of spatial solitons. Our experimental results are confirmed by...

Light bullets in Bessel optical lattices with spatially modulated nonlinearity.

We address the stability of light bullets supported by Bessel optical lattices with out-of-phase modulation of the linear and nonlinear refractive indices. We show that spatial modulation of the nonlinearity significantly modifies the shapes and stability domains of the light bullets. The addressed bullets can be stable, provided that the peak intensity does not exceed a critical value. We show...

Rotary dipole-mode solitons in Bessel optical lattices

We address Bessel optical lattices of radial symmetry imprinted in cubic Kerr-type nonlinear media and show that they support families of stable dipole-mode solitons featuring two out-of-phase light spots located in different lattice rings. We show that the radial symmetry of the Bessel lattices affords a variety of unique soliton dynamics including controlled radiation-free rotation of the dip...

Light propagation and localization in modulated photonic lattices and waveguides

We review both theoretical and experimental advances in the recently emerged field of modulated photonic lattices. These artificial periodic dielectric structures provide a powerful tool for the control of the fundamental aspects of light propagation. Photonic lattices are arrays of coupled optical waveguides, where the light propagation becomes effectively discretized. The discretized nature o...
