Reflection and refraction of Airy pulses at a moving step refractive-index boundary are investigated. A comb-like reflected spectrum and an Airy-like transmitted spectrum are formed as an Airy pulse crosses a temporal boundary without initial group velocity mismatch or initial central frequency shift. The reflected and refracted pulses are significantly influenced by the location of temporal boundary and time-dependent refractive index change. The energy of each lobe of the comb-like reflected spectra can be controlled by changing the value of decay factor of the Airy pulse. In the case of an Airy pulse with an initial launch frequency shift, the reflected and refracted frequency shifts depend on the dispersion relation of the medium. The results can be used in potential applications involving optical manipulation.

“…For example, in 2019, the study of anomalous interactions of Airy beams in the fractional nonlinear SE provided an alternative mechanism to control respiration soliton production [31]. Similarly, Airy beam interactions in linear potential [32], nonlocal nonlinear media [33] and kerr media [34,35] have been studied. Additionally, the FSE is also of great research value for modulation instability.…”

In this paper, the propagation dynamics of the Pearcey Gaussian beam modeled by the fractional Schrödinger equation in linear potential have been investigated. Different from the propagation properties of the Pearcey Gaussian beam described by the standard Schrödinger equation, the diffraction-free phenomenon which is presented under the fractional Schrödinger equation with linear potential or not, is influenced by Lévy index. When the linear potential is considered, the periodic evolution of the Pearcey Gaussian beams is given, and results show that transmission period is inversely proportional to the linear potential coefficient. And the direction of beam propagation can be controlled by the symbol of linear potential parameters. The propagation of incident beam with transverse wave velocity have been studied. Moreover, the chirp does not influence the evolution period of the Pearcey Gaussian beam but the intensity distribution. These properties can be well implemented to the promising applications of Pearcey Gaussian beam in optical manipulation and optical switch.

“…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.
