“…The nonmonotonic chirp induced by SPM gives rise to the overlapping between different frequencies in the pulse tails at the normal dispersion regime [2]. This situation leads to nonlinear frequency mixing through χ 3 susceptibility.…”

Abstract:In this work we recognize new strategies involving optical wave-breaking for controlling the output pulse spectrum in nonlinear fibers. To this end, first we obtain a constant of motion for nonlinear pulse propagation in waveguides derived from the generalized nonlinear Schrödinger equation. In a second phase, using the above conservation law we theoretically analyze how to transfer in a simple manner the group-velocity-dispersion curve of the waveguide to the output spectral profile of pulsed light. Finally, the computation of several output spectra corroborates our proposition.

“…Finally, another aspect we stress is that the dynamics undergone in the anomalous dispersive fiber of the soliton regenerator leads to a soliton-like compression [21,26], which is fundamentally different from the continuous temporal broadening undergone in the normal regime [25].…”

-In this work, we report scaling rules for the design of an all-fibered soliton-based power limiter for reamplification and reshaping (2R) regeneration process. In particular, we propose general guidelines to fix the optimum fiber length and initial power of the regenerator. We quantitatively point out the optical power limiting effect of the device enabling a significant reduction of the amplitude jitter of a degraded signal. Influence of the initial level of amplitude jitter is discussed and the results are compared with a self-phase modulation-based configuration working in the normal dispersion regime. Realistic numerical simulations in the context of 160 Gbit/s signals confirm that an efficient improvement of the signal quality can be achieved by means of such a device.

“…According to the initial conditions of the input pulse, the initial stage of nonlinear dynamics in the fiber, where Kerr-induced self-phase modulation (SPM) dominates over GVD, may be very different. Indeed, input pulses with a negative chirp coefficient will experience spectral compression as a result of SPM [15,28,29], whereas for initially positively chirped (or Fourier transform-limited) pulses, spectral broadening will drive the nonlinear dynamics and eventually lead to optical wave-breaking [30]. Moreover, propagation in the nonlinear fiber is impacted by both GVD and SPM effects, which are characterized by the respective coefficients 2 and .…”

“…2 that there are three different regions of parameter space that support the formation of a parabolic pulse with the desired duration. The region featuring normal input chirping corresponds to a transient state of the nonlinear dynamic pulse evolution in the fiber toward wave breaking [18,30,45]. The region featuring low input powers (N below 2) and large propagated lengths corresponds to a long-term far-field evolution regime in the fiber characterized by the formation of pulses of a spectronic nature [20,21,46].…”

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.
