Abstract
In this review we present the current status of the theory of dissipative optical solitons — light packets localized due to the balance of inflow (positive dissipation) and outflow (negative dissipation) of energy, and give references on the experiments in the field. We mention various mechanisms of radiation localization and the premises leading to this concept, and briefly compare the physics and properties of conservative, under conditions of negligible dissipation, and dissipative, with the balance of energy inflow and outflow, optical solitons. We shortly discuss the general properties of electromagnetic pulses and the formulation of paraxial radiation propagation in dissipative media. The characteristics of two important classes of spatial and spatiotemporal dissipative optical solitons are described in detail: those in driven wide-aperture nonlinear interferometers and in relative laser schemes without and with driving. An example of what is apparently the only exactly solvable problem in the field is given, clearly demonstrating the connection of these solitons with optical bistability and switching waves. The nontrivial internal structure of the solitons under consideration, related to the distribution of radiation energy fluxes, is explained, and the results of the analysis of the interaction of solitons and the formation of soliton complexes are presented. Particular attention is paid to the nature of the motion of these structures and its connection with their symmetry. Similarly, studied are the issues of topological optics of dissipative solitons, related to the presence of uncertainties (topological singularities) of the field phase and/or polarization state. Vector solitons are considered for 1D, 2D and 3D cases revealing their connections with the scalar ones and underlying their new dynamical features. Quantum fluctuations in dissipative solitons and extremely short solitons are considered more briefly.
期刊介绍:
Physics Reports keeps the active physicist up-to-date on developments in a wide range of topics by publishing timely reviews which are more extensive than just literature surveys but normally less than a full monograph. Each report deals with one specific subject and is generally published in a separate volume. These reviews are specialist in nature but contain enough introductory material to make the main points intelligible to a non-specialist. The reader will not only be able to distinguish important developments and trends in physics but will also find a sufficient number of references to the original literature.
