Asymmetric partially coherent solitons in saturable nonlinear media.
نویسندگان
چکیده
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 many diffraction lengths without changes, but that collisions change their shape and may split them apart.

Collision-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 ...

Incoherent solitons are partially coherent optical beams propagating without changing their shape in materials with a slow nonlinear response [1, 2]. Such nonlinear materials respond to the time averaged light intensity, which means that even though the phase of the partially coherent light beam fluctuates randomly, it still leads to a smooth light-induced refractive index change and subsequent...
متن کاملPartially Coherent Solitons on a Finite Background
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 com...
متن کاملLattice-supported surface solitons in nonlocal nonlinear media.
We reveal that lattice interfaces imprinted in nonlocal nonlinear media support surface solitons that do not exist in other similar settings, including interfaces of local and nonlocal uniform materials. We show the impact of nonlocality on the domains of existence and stability of the surface solitons, focusing on new types of dipole solitons residing partially inside the optical lattice. We f...
متن کاملElliptic incoherent solitons in saturable nonlinear media.
We identify elliptic incoherent spatial solitons in isotropic saturable nonlinear media. These solitary states are possible, provided that their correlation function is anisotropic. The propagation dynamics of this new class of solitons are investigated by use of numerical simulations. We find that, during a collision event of two such elliptic solitons, their intensity ellipse rotates, and at ...
