By means of direct simulations and theoretical analysis, we study the nonlinear propagation of truncated Airy pulses in an optical fiber exhibiting both anomalous second-order and strong positive third-order dispersions (TOD). It is found that the Airy pulse first reaches a finite-size focal area as determined by the relative strength of the two dispersion terms, and then undergoes an inversion transformation such that it continues to travel with an opposite acceleration. The system notably…

Role of initial chirp and dispersion on Airy pulse propagation in an optical single-mode fiber.
The change rule of the main lobe and peak intensity with the pulse propagation distance and the position of the breakup area is found in order to understand the importance of the initial pulse chirp.

Spectrum to distance mapping via nonlinear Airy pulses.
The frequency shift of Airy pulses can be precisely controlled by simply acting on the spectral cubic phase structure without the need to alter the fiber length.
Pulse spreading in a single-mode fiber due to third-order dispersion.
Pulse spreading in a single-mode optical fiber is discussed taking into account the third-order dispersion term of the waveguide when the light source is modulated by a Gaussian pulse. A general
Soliton shedding from Airy pulses in Kerr media.
Simulation and analysis of the propagation of truncated temporal Airy pulses in a single mode fiber in the presence of self-phase modulation and anomalous dispersion as a function of the launched Airy power and truncation coefficient shows that the Airy pulse continues to exhibit the unique property of acceleration in time.
Reshaping the trajectory and spectrum of nonlinear Airy beams.
We demonstrate theoretically and experimentally that a finite Airy beam changes its trajectory while maintaining its acceleration in nonlinear photorefractive media. During this process, the spatial

A mechanism for creating a Newton’s cradle (NC) in nonlinear light wave trains under the action of the third-order dispersion (TOD) is demonstrated. The formation of the NC structure plays an

Causality effects on accelerating light pulses.
It is found that, whereas decelerating pulses can asymptotically reach zero group velocity, pulses that accelerate towards infinite group velocity inevitably break up, after a specific critical point.
