“…With increasing currents more locations reach the critical detuning value and additional LCS switch on, whereas the LCS formed originally may give way to high-order compound states and extended, off-axis lasing states [64,85]. Typical length scales of disorder are about 10 µm and they span some tens of GHz [64] in line with the results from other devices in the literature [63,92,93]. A simple calculation shows that a monolayer variation of ∆ L ≈ 0.3 nm corresponds to a frequency variation of ∆ ν ≈ 76 GHz.…”

Self-localized states or dissipative solitons have the freedom of translation in systems with a homogeneous background. When compared to cavity solitons in coherently driven nonlinear optical systems, laser cavity solitons have the additional freedom of the optical phase. We explore the consequences of this additional Goldstone mode and analyze experimentally and numerically frequency and phase locking of laser cavity solitons in a vertical-cavity surface-emitting laser with frequency-selective feedback. Due to growth-related variations of the cavity resonance, the translational symmetry is usually broken in real devices. Pinning to different defects means that separate laser cavity solitons have different frequencies and are mutually incoherent. If two solitons are close to each other, however, their interaction leads to synchronization due to phase and frequency locking with strong similarities to the Adler-scenario of coupled oscillators.

“…(For overviews on this topic, see [3]- [9].) Important examples of stripe and hexagon formations and competition have been reported in various optical systems: Kerr media [10], [11], passive systems [12]- [16], liquid-crystal light valve with feedback [17], counterpropagating beams in a nonlinear medium [18], [19], spinatomic systems [20], quadratic media [21]- [25], bulk and quantum-well GaAlAs microresonators [26], and active media [27]- [29].…”

Abstract-We analytically and numerically study the role of the homogeneous zero mode on the interaction between two modulational instabilities. Periodic and localized structures (LSs) are considered in two transverse dimensions. We consider a real-order parameter description for a passive optical cavity driven by an external coherent field, valid close to the onset of optical bistability. A global description of pattern formation in both monostable and bistable regimes is given. We show that the interaction between the modulational modes and the zero mode modifies the existence and the stability of diffractive patterns. In particular, this interaction induces a coexistence between two different types of phase locked hexagonal structures. We also consider the interaction between two separated LSs. An analytical expression for the interaction potential in terms of modified Bessel functions is derived. Numerical simulations confirm the analytical predictions.Index Terms-Cavity solitons, localized structures, periodic patterns, spatial modulational instability, stability of interacting solitons.

“…Optical patterns such as rolls, rhombs, or hexagons have been observed in optically driven passive GaAs/GaAlAs vertical-cavity microresonators, depending on the wavelength detuning between input and cavity fields. Cavity thickness fluctuations have been shown to contribute to the pattern selection [199]. The basic modelling of VCSELs is still a hot topic and here again many models (many of them claiming to be comprehensive!)…”
