A soliton perturbed by higher-order dispersion terms can transfer power to a dispersive wave when they share a common phase velocity. This dispersive wave can be located several hundreds of nanometers away from the soliton carrier wavelength. We numerically study this phenomenon in a double-core photonic crystal fiber pumped at 1064 nm: the presence of a large quantity of short pulses due to the pump pulse break-up and the dispersion profile lead to the growth of a dispersive wave at 1535 nm whose amplitude is comparable to the pump. Preliminary experiments confirm our predictions.

Abstract
A soliton perturbed by higher-order dispersion terms can transfer power to a dispersive wave when they share a common phase velocity. This dispersive wave can be located several hundreds of nanometers away from the soliton carrier wavelength. We numerically study this phenomenon in a double-core photonic crystal fiber pumped at 1064 nm: the presence of a large quantity of short pulses due to the pump pulse break-up and the dispersion profile lead to the growth of a dispersive wave at 1535 nm whose amplitude is comparable to the pump. Preliminary experiments confirm our predictions.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
