Optical solitons in multimode fibers exhibit complex dynamics, and peculiar characteristics in terms of pulse duration and energy, which distinguish them from their single-mode counterparts. We propose a theory for Raman-induced soliton self-frequency shift in multimode fibers, that is compared against experimental data of 1-km multimode soliton propagation. Specific values of pulsewidth and energy are found, at which solitons show long-distance stability and better correspondence with the theory of self-frequency shift; those values depend on the input wavelength, but are not related to the duration of the input pulse. Raman delay is affected by a jitter, characterized by a Gaussian statistical distribution, whose standard deviation tends to stabilize to a constant value for increasing pulse energies.

Abstract
Optical solitons in multimode fibers exhibit complex dynamics, and peculiar characteristics in terms of pulse duration and energy, which distinguish them from their single-mode counterparts. We propose a theory for Raman-induced soliton self-frequency shift in multimode fibers, that is compared against experimental data of 1-km multimode soliton propagation. Specific values of pulsewidth and energy are found, at which solitons show long-distance stability and better correspondence with the theory of self-frequency shift; those values depend on the input wavelength, but are not related to the duration of the input pulse. Raman delay is affected by a jitter, characterized by a Gaussian statistical distribution, whose standard deviation tends to stabilize to a constant value for increasing pulse energies.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
