We review the properties of optical spatial dissipative solitons (SDS). These are stable, self-localized optical excitations sitting on a uniform, or quasi-uniform, background in a dissipative environment like a nonlinear optical cavity. Indeed in optics they are often termed 'cavity solitons'. We discuss their dynamics and interactions in both ideal and imperfect systems, making comparison with experiments. SDS in lasers offer important advantages for applications. We review candidate schemes and the tremendous recent progress in semiconductor-based cavity soliton lasers. We examine SDS in periodic structures, and we show how SDS can be quantitatively related to the locking of fronts. We conclude with an assessment of potential applications of SDS in photonics, arguing that best use of their particular features is made by exploiting their mobility, e.g. in all-optical delay lines.

“…The bifurcation structure and temporal dynamics of these dark solitons, also called "platicons", have been recently studied [15][16][17], and their origin is intimately related to the locking of switching waves (SWs) connecting coexisting homogeneous state solutions of high and low intensity [16][17][18]. Such dissipative localized structures have also been studied in spatial systems, both in one and two dimensions, with different nonlinearities [19,20]. The generation of dark pulse Kerr frequency combs has been achieved experimentally by several groups [21][22][23].…”

Using the Lugiato-Lefever model, we analyze the effects of third-order chromatic dispersion on the existence and stability of dark-and bright-soliton Kerr frequency combs in the normal dispersion regime. While in the absence of third-order dispersion only dark solitons exist over an extended parameter range, we find that third-order dispersion allows for stable dark and bright solitons to coexist. Reversibility is broken and the shape of the switching waves connecting the top and bottom homogeneous solutions is modified. Bright solitons come into existence thanks to the generation of oscillations in the switching-wave profiles. Temporal oscillatory instabilities of dark solitons are suppressed in the presence of sufficiently strong third-order dispersion, while bright solitons are never found to oscillate in time. As a result of third-order dispersion both bright and dark solitons are found to move with a velocity that depends on their width.

Abstract. The properties of quadratic spatial solitons generated in periodically poled lithium tantalite in the femtosecond regime are investigated. By using only a fundamental frequency beam as the input to excite quadratic spatial solitons, single and spatially anisotropic multiple solitons are generated. Our experiments demonstrate that the number of solitons is dependent on the input power. In the experiment, beam narrowing occurs first, leading to single-soliton generation. The threshold for multiple solitons is around 1.5 mW. The number of solitons does not increase indefinitely with input power. Multiple soliton generation only occurs in the input power range of 1.5 to 6.3 mW. The number of solitons decreases to 1 when the input power is 6.3 mW. The temporal and spectral characteristics of the spatial solitons are measured by using the GRENOUILLE technique. © IntroductionWith the development of high power ultrafast lasers, quadratic nonlinear crystals have become widely used in nonlinear optics, and the quadratic spatial soliton is one of the most intriguing nonlinear effects.1-10 One of the unique features of quadratic solitons is that they consist of all of the beams strongly coupled together by the second-order nonlinearity. Second-harmonic generation (SHG) processes can result in generation of quadratic spatial soliton. With their particlelike behavior in interactions and collisions, spatial solitons have the potential to be used for all-optical data processing, pattern recognition, and parallel information storage.
