“…The effects of third-order [67,68] and fourth-order [69][70][71] diffraction/dispersion on the propagation of Airy pulses/beams have been investigated in detail. We have also studied the interactions of Airy beams in local Kerr, saturable, and nonlocal media with fourth-order diffraction [72].…”

We investigate the interactions of in-phase Airy beams modulated by a fundamental Gaussian beam and fourth-order diffraction in Kerr nonlinear media. Directly numerical simulations show that normal (anomalous) fourth-order diffraction and an in-phase (out-of-phase) Gaussian beam affect the interactions of solitons generated from Airy beams in unique ways. Different from previous results, suggesting that interactions of in-phase (out-of-phase) conventional beams are always attractive (repulsive), many anomalous interactions of Airy beams are obtained. Stable breathing Airy soliton pairs can be formed with fourth-order diffraction and a fundamental Gaussian beam.

“…Additionally, generation of Airy pulses by dispersion management has also been reported [20]. Supercontinuum generation [21,22], and soliton shedding in presence of different nonlinearities are studied rigorously [23][24][25][26][27][28][29]. Additionally, control of the emergent soliton dynamics through the initial pulse parameters has also been explored [30].…”

We numerically investigate the propagation dynamics of truncated Airy pulse in the presence of external harmonic potential. These optical potentials are generated by co-propagating time-dependent strong pump wave that interacts with the weak signal pulse through cross-phase modulation (XPM). We demonstrate that Airy pulse trajectory can be manipulated by utilizing a sinusoidal optical potential and soliton shedding is observed in both normal and anomalous group velocity dispersion (GVD). The intensity of the emergent soliton depends upon the strength of the potential. Additionally, the potential strength significantly affects the oscillations and temporal position of the peak intensity of the soliton. Further, the impact of the truncation parameter on the Airy pulse accelerating tail and spectrum is explored. Importantly, we have numerically explored the evolution of the temporal chirp of the pulse in various conditions. The temporal chirp is almost zero at the position where the intensity peaks. Also, we show that relative phase of the optical harmonic potential play a vital role in the soliton formation.

The interaction between two Airy pulses propagating at different wavelengths is numerically investigated. The periodically varying peak intensity of the soliton that emerges from stronger Airy pulse (pump pulse) leads to the formation of periodic temporal boundary. The relatively weaker Airy pulse (probe pulse) on interaction with this boundary gets partially reflected as well as transmitted. As a result, the probe pulse spectrum splits into two parts‐ the reflected pulse spectrum undergoes redshift while transmitted pulse exhibits blueshift. The probe pulse witnesses maximum reflection when point of interaction lies on the intensity maxima of the emergent soliton from pump Airy pulse. On the other hand, maximum transmission occurs when probe Airy pulse interacts at the intensity minima of the soliton. The reflection and transmission processes can be manipulated by tuning the time delay between pump and probe Airy pulses. In the case of a sufficiently intense pump pulse, the temporal boundary mimics the artificial optical event horizon, and the weak probe Airy pulse is completely reflected. This phenomenon is equivalent to the temporal version of total internal reflection. The results of the study hold potential applications in optical manipulation and temporal waveguiding.
