Partially Coherent Solitons on a Finite Background
نویسندگان
چکیده
We have found a new class of exact solutions for multicomponent partially coherent solitons in photorefractive media with a drift mechanism of nonlinear response. Their novel feature is that the composite M-component sech-shaped soliton is located on a constant-background plane wave. The solutions are characterized by two free parameters and these are related to the maximum intensity of the composite soliton and to the amplitude of the background. [S0031-9007(99)08778-5]

Asymmetric partially coherent solitons in saturable nonlinear media.
We investigate theoretically properties of partially coherent solitons in optical nonlinear media with slow saturable nonlinearity. We have found numerically that such a medium can support spatial solitons which are asymmetric in shape and are composed of only a finite number of modes associated with the self-induced waveguide. It is shown that these asymmetric spatial solitons can propagate ma...
متن کاملExperiments on partially coherent photorefractive solitons
We provide an overview of experimental studies on partially coherent spatial solitons in photorefractive materials, including the first experimental demonstration of bright and dark incoherent solitons, incoherent vortex solitons, Y-junction dark solitons and anti-dark solitons, and pixel-like incoherent soliton arrays. These solitons are created with partially spatially incoherent light beams ...
متن کاملSingle-shot observation of optical rogue waves in integrable turbulence using time microscopy
Optical fibres are favourable tabletop laboratories to investigate both coherent and incoherent nonlinear waves. In particular, exact solutions of the one-dimensional nonlinear Schrödinger equation such as fundamental solitons or solitons on finite background can be generated by launching periodic, specifically designed coherent waves in optical fibres. It is an open fundamental question to kno...
متن کاملCollision-induced shape transformations of partially coherent solitons
Partially coherent solitons are objects which have recently attracted a great deal of attention @1–10#. Focusing of the spatially partially coherent beams has been suggested as early as in 1967 @11# and studied subsequently in @12,13#. On the other hand, temporally incoherent solitons have been considered in the original works of Hasegawa @14–16#, both for plasma waves and for nonlinear pulses ...
متن کاملDiscrete solitons and soliton-induced dislocations in partially coherent photonic lattices.
We investigate both experimentally and theoretically the interaction between a light beam and a photonic lattice optically induced with partially coherent light. We demonstrate a clear transition from two-dimensional discrete diffraction to discrete solitons in such a partially coherent lattice and show that the nonlinear interaction process is associated with a host of new phenomena including ...
