Numerical methods for generation and characterization of disordered aperiodic photonic lattices
(Optical Soc Amer, Washington, 2022)
We introduce numerical modeling of two different methods for the deterministic randomization of two-dimensional aperiodic photonic lattices based on Mathieu beams, optically induced in a photorefractive media. For both ...
Interdimensional radial discrete diffraction in Mathieu photonic lattices
(Optica Publishing Group, 2023)
We demonstrate transitional dimensionality of discrete diffraction in radial-elliptical photonic lattices. Varying the order, characteristic structure size, and ellipticity of the Mathieu beams used for the photonic lattices ...
Counterpropagating beams in nematic liquid crystals
(Optics Express, 2006)
The behavior of counterpropagating self-trapped optical beam structures in nematic liquid crystals is investigated. A time-dependent model for the beam propagation and the director reorientation in a nematic liquid crystal ...
Soliton formation by decelerating interacting Airy beams
(Optics Express, 2015)
We demonstrate a new type of soliton formation arising from the interaction of multiple two-dimensional Airy beams in a nonlinear medium. While in linear regime, interference effects of two or four spatially displaced Airy ...
Spatiotemporal optical instabilities in nematic solitons
(Optics Express, 2005)
We investigate numerically the propagation of self-trapped optical beams in nematic liquid crystals. Our analysis includes both spatial and temporal behavior. We display the formation of stable solitons in a narrow threshold ...
