“…Recently, Vertical-Cavity Surface-Emitting Lasers (VCSELs) have attracted considerable interest for CS studies and applications because they are inherently made with a short (single longitudinal mode) cavity, which can be transversely quite large [15]. In the first demonstrations of the existence of CSs in broad-area VCSELs, external * c.schelte@uib.cat † gurevics@uni-muenster.de coherent light with an appropriate frequency is injected to create the required "pinning region" and CSs have been found both below [16,17] and above [18] the lasing threshold. Utilizing the specific polarization properties of VCSELs [19], spatially localized structures have also been created in 40 µm-diameter VCSELs [20], as well as in 80 µm-diameter VCSELs lasing on a high transverseorder flower mode [21,22].…”

We consider a wide-aperture surface-emitting laser with a saturable absorber section subjected to time-delayed feedback. We adopt the mean-field approach assuming a single longitudinal mode operation of the solitary VCSEL. We investigate cavity soliton dynamics under the effect of timedelayed feedback in a self-imaging configuration where diffraction in the external cavity is negligible. Using bifurcation analysis, direct numerical simulations and numerical path continuation methods, we identify the possible bifurcations and map them in a plane of feedback parameters. We show that for both the homogeneous and localized stationary lasing solutions in one spatial dimension the time-delayed feedback induces complex spatiotemporal dynamics, in particular a period doubling route to chaos, quasiperiodic oscillations and multistability of the stationary solutions.

“…amplifying, [11,13]) media. Above threshold, CS have been demonstrated in lasers with injected signal [14,15]. In all these cases, the frequency and phase of the CS is locked to that of the injected field, and so is sensitive to any phase variations or fluctuations.…”

Realization of a Semiconductor-Based Cavity Soliton Laser

The realization of a cavity soliton laser using a vertical-cavity surface-emitting semiconductor gain structure coupled to an external cavity with a frequency-selective element is reported. Alloptical control of bistable solitonic emission states representing small microlasers is demonstrated by injection of an external beam. The control scheme is phase-insensitive and hence expected to be robust for all-optical processing applications. The motility of these structures is also demonstrated.

“…In the seminal experiment on CS in VCSELs [50,58], a large cavity resonance gradient of 2.34 GHz/μm was measured which prevented the observation of cavity solitons over the entire VCSEL surface. Later, improvements in the growth conditions enhanced the VCSEL uniformity of about one order of magnitude (0.4 GHz/μm [59]) and allowed the manipulation of CS over the whole transverse extent of the VCSEL. As for the pump uniformity, the bottom emitting structure allows to achieve a very good uniformity at the center of the device, whereas the borders suffer the well-known current crowding effect [60].…”

We review advances on the experimental study of cavity solitons in VCSELs in the past decade. We emphasize on the design and fabrication of electrically or optically pumped broad-area VCSELs used for CSs formation and review different experimental configurations. Potential applications of CSs in the field of photonics are discussed, in particular the use of CSs for all-optical processing of information and for VCSELs characterization. Prospects on self-localization studies based on vertical cavity devices involving new physical mechanisms are also given.
