“…Numerous examples have been found in nonlinear optical resonators with coherent forcing (they often receive the name of spatial or temporal cavity solitons) [1][2][3][4][5][6] but also in laser systems [7][8][9][10] . In the latter case, the phase of the electric field is free to evolve in the course of time and a paradigmatic model is the cubic-quintic Ginzburg-Landau equation 7,[11][12][13] .…”

Optical localized states are usually defined as self-localized bistable packets of light, which exist as independently controllable optical intensity pulses either in the longitudinal or transverse dimension of nonlinear optical systems. Here we demonstrate experimentally and analytically the existence of longitudinal localized states that exist fundamentally in the phase of laser light. These robust and versatile phase bits can be individually nucleated and canceled in an injection-locked semiconductor laser operated in a neuron-like excitable regime and submitted to delayed feedback. The demonstration of their control opens the way to their use as phase information units in next-generation coherent communication systems. We analyse our observations in terms of a generic model, which confirms the topological nature of the phase bits and discloses their formal but profound analogy with Sine-Gordon solitons.

“…These techniques necessitate either a small area cavity, a fast saturable absorber, or a complex electrical design and are not suited for CS studies. An original design for a vertical cavity laser with intracavity saturable absorber has been proposed in [73]. Using the same technique as explained before, a cavity having a saturable absorber section and a gain section is designed.…”

“…Experimentally, CS have been observed in several systems based on photorefractive crystals [48], Na vapors [46], liquid crystal light valves [49,74], semiconductor optical amplifiers [50,68], and lasers [54,55,73,75]. In the latter, most experiments have been done in VCSELs, because their short cavity and large diameter insure a Fresnel number large enough to avoid the formation of patterns correlated over the whole extension of the system.…”

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.
