Light localization in azimuthally modulated Bessel photonic lattices

چکیده
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 direct numerical simulations.

Observation of light localization in modulated Bessel optical lattices.
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 a...
متن کاملComposite vortex-ring solitons in Bessel photonic lattices
We reveal the existence of dynamically stable composite topological solitons in Bessel photonic lattices imprinted in focusing Kerr-type nonlinear media. The new stable composite solitons are made of a vortex-ring with unit topological charge incoherently coupled to a fundamental soliton. The stabilization of the otherwise highly azimuthally unstable vortex-rings is provided under suitable cond...
متن کاملLight 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...
متن کاملSoliton topology versus discrete symmetry in optical lattices.
We address the existence of vortex solitons supported by azimuthally modulated lattices and reveal how the global lattice discrete symmetry has fundamental implications on the possible topological charges of solitons. We set a general "charge rule" using group-theory techniques, which holds for all lattices belonging to a given symmetry group. Focusing on the case of Bessel lattices allows us t...
متن کاملBending light via adiabatic optical transition in longitudinally modulated photonic lattices
Bending light in a controllable way is desired in various applications such as beam steering, navigating and cloaking. Different from the conventional way to bend light by refractive index gradient, transformation optics or special beams through wavefront design such as Airy beams and surface plasmons, we proposed a mechanism to bend light via resonant adiabatic optical transition between Floqu...
