“…Figure 76 shows snapshots of bright and dark (∼10 µm diameter) solitons, at the large (negative) resonator detuning. Their shape/size is independent of the shape/intensity of the driving beam [67]. This independence of boundary conditions (to their 'self-localization') characterizes solitons, as opposed to switched domains.…”

We review pattern formation in optical resonators. The emphasis is on 'particle-like' structures such as vortices or spatial solitons. On the one hand, similarities impose themselves with other fields of physics (condensed matter, phase transitions, particle physics, fluds/super fluids). On the other hand the feedback is led by the resonator mirrors to bi-and multi-stability of the spatial field structure, which is the basic ingredient for optical information processing.The spatial dimension or the 'parallelism' is the strength of optics compared to electronics (and will have to be employed to fully use the advantages optics offers in information processing). But even in the 'serial' processing tasks of telecoms (e.g. information buffering) spatial resonator solitons can do better than the schemes proposed so far-including 'slow light'.Pattern formation in optical resonators will likely be the key to brain-like information processing like cognition, learning and association; to complement the precise but limited algorithmic capabilities of electronic processing. But even in the short term it will be useful for solving serial optical processing problems.The prospects for technical uses of pattern formation in resonators are one motivation for this research. The fundamental similarities with other fields of physics, on the other hand, inspire transfer of concepts between fields; something that has always proven fruitful for gaining deeper insights or for solving technical problems.

“…The fundamental laser solitons have been observed experimentally in a dye laser with a saturable absorber [6,9,10] in a bistable semiconductor laser [11] and in a laserlike two-wave-mixing oscillator with a saturable absorber [12]. It was shown that they can be switched on and off by external addressing pulses in different transverse locations and they can move in the phase gradient (figure 3).…”

We present an overview of theoretical and experimental works on self-sustaining localized structures—spatial solitons—which can be formed in optical bistable oscillators with laser and/or parametric gain. The main attention is paid to the existence and dynamical properties of spatial solitons containing phase and polarization topological defects including vortices, points of circular polarizations and lines of linear polarization, domain walls and composed domain walls with Néel point topological defects.

“…The regions themselves may be static or moving. Localized patterns have been discovered in many physical systems and their models. − However, only a few examples are known in reaction−diffusion (RD) systems, namely, autonomous wave segments, breathing (oscillating) spots, localized oscillatory clusters, localized wave segments controlled by global negative feedback, oscillons (localized oscillatory spots), localized stationary spots, and localized waves . The main difference between autonomous wave segments and localized waves is that the former appear spontaneously and are observed as two or more wave segments moving in the same direction, whereas localized waves appear due to special initial conditions and can move in directions determined by the initial conditions (in particular, in opposite directions) …”
