“…A detailed characterization of such interactions is beyond the scope of this work. For a more in-depth theoretical and experimental study of bound states of solitons in the presence of TOD in the Lugiato-Lefever equation, we refer to [52,53]. In these works, solitons interact through their oscillatory tails and bound states can form as a result of the stable locking of such tails.…”

Using the Lugiato-Lefever model, we analyze the effects of third-order chromatic dispersion on the existence and stability of dark-and bright-soliton Kerr frequency combs in the normal dispersion regime. While in the absence of third-order dispersion only dark solitons exist over an extended parameter range, we find that third-order dispersion allows for stable dark and bright solitons to coexist. Reversibility is broken and the shape of the switching waves connecting the top and bottom homogeneous solutions is modified. Bright solitons come into existence thanks to the generation of oscillations in the switching-wave profiles. Temporal oscillatory instabilities of dark solitons are suppressed in the presence of sufficiently strong third-order dispersion, while bright solitons are never found to oscillate in time. As a result of third-order dispersion both bright and dark solitons are found to move with a velocity that depends on their width.

“…The uniform variation of detuning parameter in the semiconductor resonator (i.e., VCSEL) also sets a gradient [5]. Any gradient or inhomogeneity in the media leads to the movement of CS [24]. Gradients in the cavity can be introduced through injection beam [23], time delay, feedback field strength [15], [16], feedback field phase [14] or by generating gradients in the cavity background [5].…”

Abstract-We present an improved model for cavity soliton generation by coupling frequency-selective feedback to a verticalcavity surface emitting laser with a saturable absorber. The frequency-selective feedback is found to lower down the threshold pump power for cavity soliton generation and eventually to broaden the stability regime. A new dynamics of cavity solitons is revealed in form of "all-optical push-broom effect." Also, stable bound states of cavity solitons that resemble linear diatomic and polyatomic molecules are predicted with their stability regions marked. The findings can be exploited for experimental realization of a soliton force microscope and all-optical memory devices.
