Dynamics of coupled dark and bright optical solitons.

چکیده
We theoretically examine the interaction between two solitons in a double-mode optical fiber. The bound state between two solitons of different modes is investigated, including both dark and bright solitons. It is shown that interaction between dark solitons as well as between bright solitons is always attractive, but the interaction between bright and dark solitons may be repulsive. Analytical results are in agreement with numerical ones.

Spatial soliton pairs in an unbiased photovoltaic-photorefractive crystal circuit
: Optical separate spatial dark and bright soliton pairs in steady-state case in one dimension, for a series circuit consisting of two-photon photorefractive (PR) crystal are investigated. Each crystal can be supported the spatial soliton, and at least one must be photovoltaic. The two solitons are known collectively as separate spatial soliton pairs with dark–dark, bright–dark and bright–brigh...
متن کاملDark Optical Solitons: Physics and Applications
We present a detailed overview of the physics and applications of optical dark solitons: localized nonlinear waves (or ‘holes’) existing on a stable continuous wave (or extended finite-width) background. Together with the traditional problems involving properties of dark solitons of the defocusing cubic nonlinear Schrödinger equation, we also describe recent theoretical results on optical vorte...
متن کاملUltraslow bright and dark solitons in semiconductor quantum wells
We study the low-intensity light pulse propagation through an asymmetric double quantum well via Fanotype interference based on intersubband transitions. The propagation of the pulse across the quantum well is studied analytically and numerically with the coupled Maxwell-Schrödinger equations. We show the generation of ultraslow bright and dark optical solitons in this system. Whether the solit...
متن کاملPropagation of Incoherently Coupled Soliton Pairs in Photorefractive Crystals and their Self-Deflection
Propagation of incoherently soliton pairs in photorefractive crystals under steady-state conditions is studied. These soliton states can be generated when the two mutually incoherent optical beams with the same polarization and wavelength incident on the biased photorefractive crystal. Such soliton pairs can exist in bright-bright, dark-dark, gray-gray as well as in bright-dark types. In this p...
متن کاملStable vector solitons composed of bright and dark pulses.
The vector optical solitons composed of bright and dark pulses are analyzed. It is shown that in the smallamplitude limit a bound state of these solitons is described by the generalized Zakharov system, which supports coupled soliton solutions, and under special conditions it reduces to an integrable model. In the limit in which the integrable model approximation is valid, numerical simulations...
