“…Hence, this scheme has potential for all-optical photonic switching. In particular, a version of this experiment using a broad-area laser is attractive for the investigation of the possibility of cavity solitons [29].…”

“…In the case of broad-area devices, bistability could be favorably explored to excite spatial localized emission states (cavity solitons) by an external focused control beam (cf. to [29] for preliminary results). Cavity solitons are considered to be attractive as "bits" for future all-optically and potentially massively parallel information processing schemes [23].…”

The emission characteristics of a vertical-cavity surface-emitting laser (VCSEL) operated in a single-transverse mode and coupled to an external cavity with a diffraction grating as a frequency-selective element are analyzed experimentally, numerically and analytically. The experiments yield a rather abrupt turn-on of the VCSEL to a high-amplitude emission state and hysteresis phenomena. The experimental results are explained by numerical simulations and analytical calculations demonstrating the possibility of bistability between lasing and non-lasing states close to threshold. Hence, the scheme might be useful in all-optical photonic switching applications. A detailed bifurcation analysis near threshold is given by superimposing the numerical results with analytical steady-state curves. The mode selection and switching behavior obtained in the simulations can be interpreted from the point of view of the preference of states with the minimal total losses.

“…A further scheme exhibiting the spatial solitons in a broad area electrically pumped semiconductor resonator (VCSEL) has recently been suggested: it is known that semiconductor lasers with a frequency-selective optical feedback show a subcritical (bistable) emission characteristic. Since such a bistability is a requirement for spatial solitons a corresponding experiment was carried out [87] and evidence for self-localization was obtained.…”

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.
