C. Wang, Dynamics of the divergent dark and bright solitonic channels evolved from a dark solitonlike beam in a medium with competing third- and fifth-order nonlinearities, J OPT SOC B, 18(9), 2001, pp. 1351-1355
A theoretical study has been made of the dynamics of the divergent dark and
bright solitonic channels that have evolved from a dark solitonlike beam i
n a self-defocusing medium with measurable fifth-order focusing nonlinearit
y. During perturbation the incident dark solitonlike beam with appropriate
parameters is deformed and evolves into a dark solitonic channel, emitting
additional radiation from which a bright companion channel is born. Global
propagation becomes stable and falls into a pattern of the divergent dark a
nd bright solitonic channels with desirable built-in mutual support by way
of the background that typifies the counterbalance between diffraction of t
he solitonic channels and the joint effect of the competing nonlinearities.
At this stage the energy redistribution among the solitonic channels and t
he background is retained up to a dynamic equilibrium, and the overall tran
sverse momentum is conserved. (C) 2001 Optical Society of America.
