Propagación de ondas no lineales oscuras en fibras ópticas.

In the present work the dynamics of solitary waves in optics is reported. The dynamics of these structures is governed by the nonlinear Schrödinger’s general equation. Particle-like behavior is shown, due to the interaction of dispersion and nonlinearity expressed in the nonlinear dependence on the refractive index of the optical medium. The solitons obtained are propagated in an optical fiber without altering their shape and speed and therefore can be considered as a natural means to transmit information or energy without significant losses. Their stability properties depend on the speed of solitonic waves which, in the case of nonlinear dark waves, or bubbles are subsonic. [ABSTRACT FROM AUTHOR]
