“…Quadratic, cubic, sinusoidal, step, and triangular spectral phase modulations have been exploited for realizing a variety of novel shaped pulses. [21][22][23][24] More recently, Lourdesamy et al utilized spectral pulse shaper to generate a pulse train with smooth soliton-like envelope for enhancing nonlinear effects. [25] Among these phase modulation patterns, sinusoidally spectral phase (SSP) exhibits unique characteristics because of its periodic modulation with adjustable modulation frequency and depth as well as absolute phase.…”

The dispersive waves (DWs) emitted from a Gaussian pulse with an initial sinusoidally spectral phase (SSP) modulation are investigated. By tailoring the modulation depth and frequency, the SSP results in complex pulses shape with a multipulses structure ranging from Airy‐like to pulse sequences having controllable delay and phase. These salient features are able to control and enhance the radiation frequency and energy conversion efficiency of the DWs. The resonant frequencies based on a modified phase‐matching condition are given, which agree with the numerical results obtained by solving the nonlinear Schrödinger equation directly. The results not only further extend the application of the pulse shaping technology in fiber optics, but also provide an alternative approach to manipulate the process of DWs emission which is relevant to the generation broadband supercontinuum as well as frequency comb.

The supercontinuum generation and manipulation of Airy-Gaussian pulses in a photonic crystal fiber with three zero-dispersion points are studied using the split-step Fourier method. Firstly, the spectral evolution of Airy-Gaussian pulses in four photonic crystal fibers with different barrier widths was discussed, and the optimal fiber was determined after considering the factors of width and flatness. By analyzing the mechanism of supercontinuum generation in photonic crystal fibers with single, double and three zero-dispersion points, it is found that the photonic crystal fiber with three zero-dispersion points have a larger spectral width due to the component of tunneling solitons. Then, the effects of four characteristic parameters (truncation factor a, distribution factor χ0, initial chirp C and central wavelength λ) on forming the supercontinuum spectrum of Airy-Gaussian pulses are analyzed in detail. The results show that the spectral width and energy intensity of the dispersive wave and tunneling soliton generation can be well controlled by adjusting the barrier width and initial parameters of the pulse. These research results provide a theoretical basis for generating and manipulating high-power mid-infrared supercontinuum sources.

“…[28][29][30] More recently, the temporal structure of pump pulse has also been extended from symmetric to asymmetric to control the resonant radiation, including dark and Peregrine soliton, [31,32] multimode and shock waves, [33,34] and self-accelerating pulse. [35,36] In our previous works, we have reported that the conversion efficiency and radiation frequency of DWs can be controlled by adjusting the spectral phase modulation, [37,38] which makes the shaped pulses with symmetrical spectral shapes, while their temporal profiles exhibit asymmetric structure. In particular, the asymmetric temporal structure of the shaped pulse can trigger temporal collisions that can significantly alter the intensity and shape of the resonance spectrum.…”

The process of dispersive waves (DWs) emitted from unique Pearcey Gaussian (PG) pulses with both temporal and spectral asymmetric shapes in the anomalous dispersion region of optical fiber is investigated. In contrast to symmetric pulses such as fundamental soliton (Sech) or Gaussian, the radiation amplitude and energy conversion efficiency of DWs are significantly improved by adjusting the asymmetry of the spectral distribution and the temporal oscillation structure of PG pulses. It is shown that, for the case of PG pulses, the minimum value of third-order dispersion parameter required for the emergence of DWs emission is nearly reduced 50% compared with the case of symmetric pulses. It is also shown that the radiation frequency of DWs emitted from PG pulses can be predicted by a modified phase matching condition. The theoretical predictions are in good agreement with the numerical simulations. The impact of Raman scattering effects on the DWs emission is also disclosed. The results of this study clearly reveal the impact of the inherent behaviors of PG pulses on the DWs emission, which should be relevant for applications requiring broadband light sources based on the mechanism of DWs emission.
