“…The use of nonlinear propagation in fiber to create parabolic-shaped pulses has been extensively studied in the literature, with an emphasis on fiber amplifiers [43,44]. An arbitrary pulse inserted in an active (gain) or dispersion-decreasing fiber (where a longitudinal decrease of the normal dispersion emulates linear gain) is nonlinearly attracted toward an asymptotically evolving parabolic pulse subject to certain relations (scaling) between pulse amplitude, duration and chirp parameter.…”

We present a general method to determine the parameters of nonlinear pulse shaping systems based on pulse propagation in a normally dispersive fiber that are required to achieve the generation of pulses with various specified temporal properties. The nonlinear shaping process is reduced to a numerical optimization problem over a three-dimensional space, where the intersections of different surfaces provide the means to quickly identify the sets of parameters of interest. We also show that the implementation of a machine-learning strategy can efficiently address the multi-parameter optimization problem being studied.

“…Indeed, it has been demonstrated that any initial waveform propagating under conditions of normal dispersion, non-linearity and distributed gain will evolve asymptotically into a similariton, a pulse characterized by a parabolic intensity profile with a linear positive chirp [30][31][32] . Once this typical parabolic profile is obtained, it propagates self-similarly, i.e.…”

“…3(a) the temporal intensity profiles after the nonlinear propagation in the passive or active HNLF and before spectral filtering (initial pulses having the initial power corresponding to the working points of the regenerator). The output pulse shape exhibit marked differences : the pulses obtained after propagation in the RFA clearly exhibits the parabolic signature 31,32) . On the contrary, in the passive fiber, the temporal profile is flattened as can be obtained after the wavebreaking stage 33) and which has been found to be crucial for MR behavior 11) .…”

“…The amplitude and width scaling in this case depend only on the amplifier parameters and input pulse energy. Parabolic pulses have found numerous applications in pulse amplification and compression 7 as well as in optical communications. 5,7 These include optical regeneration, 8 pulse re-timing, 9 the optimization of return-to-zero optical receivers, 10 and mitigation of linear waveform distortions.…”

Abstract. The supercontinuum (SC) generated by pumping in anomalous dispersion is sensitive to the input pulse fluctuations and pump laser's shot noises and does not possess a single-pulse waveform, so the incident pulse becomes a noise-like train of spikes. A simple method of creating pulsed lasers with either pulse-maintaining ultrabroad SC or specially shaped pulse waveforms can be implemented using all-normal-dispersion microstructured optical fibers (ANDi-MOFs). An ANDi-MOF with a simple topology and dispersion profile maximum at 800 nm was designed using the effective index method. Its properties and suitability were characterized via numerical simulation of femtosecond parabolic pulse formation and generation of an octave-spanning pulsemaintaining SC using a generalized propagation equation. The designed ANDi-MOF is suitable for resolving both problems and allows some detuning of the pulse's wavelength around 800 nm. However, a better choice for SC generation is pumping at or near the wavelength where the thirdorder dispersion becomes zero. This configuration benefits from the absence of pulse break-up under large pulse energies, which appears otherwise. The fiber can provide a low-cost method for developing supercontinuum sources and a solution to the problems of parabolic waveform formation to meet the needs of optical signal processing and pulse amplification and compression.
