Abstract :
In this letter, we analyze the relationship between four-wave mixing (FWM) and modulational instability (MI), using numerical simulations. Our results suggest that FWM dynamics interfere on MI process, shifting its maximum frequency gain. This relation may affect the performance of highly nonlinear fibers, which are being proposed to implement wavelength-conversion devices to be used in all-optical networks.
