Implication

Physics study reveals soliton train generation in multimode graded-index fibers via space-time-coupled pulses, indicating structured light can tailor nonlinear optical dynamics.

Key Points

Investigate whether injecting space-time-coupled light pulses into multimode graded-index fibers can generate controllable trains of multimode solitons.
Simulated the propagation and nonlinear interactions of space-time-coupled light pulse-beams in multimode graded-index fibers.
Tested inputs with spatial chirps and space-time optical vortices characterized by topological charge l.
Spatially chirped input pulses split under nonlinear interactions into two distinct multimode solitons composed of LP01 and LP11 spatial modes.
Space-time optical vortex injection generated a train of |l| + 1 multimode solitons, whose energy and modal profiles are governed by the absolute topological charge.
