“…Currently, multimode fibers (MMFs) have attracted substantial attention in nonlinear optics, making potential contributions to theoretical scientific research and practical applications. It provides a complicated channel for supporting thousands of modes interacting with each other when propagating [1,2]. Due to the spatial-division and mode-division multiplexing techniques [3][4][5], MMFs are regarded as a large bandwidth medium for optical fiber communication.…”

We investigate the propagation dynamics of the Peregrine soliton, a significant prototype of rogue waves, within the graded-index multimode fibers, in the absence of higher-order dispersion. The Peregrine soliton keeps the approximate evolution trend when propagating within the graded-index multimode fibers to replace the single-mode fibers when preserving the equivalent nonlinear effect. In addition, a series of dispersive waves (also called resonant radiation) can be emitted by the Peregrine soliton, perturbated by the periodic beam oscillation caused by the spatial self-imaging effect within the graded-index multimode fibers. To be more exact, the location of the multiple resonant frequencies can be predicted using the modified quasi-phase-matching conditions, which are verified by the numerically calculated results. We can also manipulate the locations of spectral sidebands and the peak power of dispersive waves by changing the self-imaging parameter of the graded-index multimode fibers. Our findings can provide a deeper comprehension of the propagation characteristic of the Peregrine soliton within the graded-index multimode fibers and provide valuable instruction for further rich nonlinear experiments.

“…As is known to all, optical field propagation in MMFs involves rich spatiotemporal dynamics and complex intermodal interactions [2,25,26]. More theoretical studies and ways are needed for a more profound understanding of complex spatiotemporal dynamic behaviors [25]. Control of physical phenomena in MMFs and their applications are in their infancy, opening opportunities to take advantage of complex nonlinear modal dynamics [27].…”

Light propagation in multimode fibers involves abundant modal dynamics. The energy flow from the intermediate modes into the fundamental and high-order modes is investigated, including the influences by the mode number and mode energy of high-order modes. It is quite surprising that random distribution of high-order modes evolves to a stationary one, indicating the behavior of an attractor. Lyapunov exponent is adopted to quantitatively discuss such attractor. The findings may pave the way to secure communications in multimode fibers.
