Abstract: The cross-phase modulation(XPM) between pulse train and continuum wave in dispersion-shifted fiber(DSF) is utilized to implement all-optical wavelength conversion.The frequency shift and broadening of continuum wave induced by XPM in DSF was experimentally observed.Then wavelength conversion was achieved through filtering by a fiber grating.The converted pulse train with repetition rate of 57.97MHz,pulse-width of 2ns and the modulation period of continuum wave of 1537nm~1560nm,almost as the same of pump pulse,was obtained.The results show that wavelength conversion based on cross-phase modulation of DSF is simple,efficient and universal with wide conversion range and high rate.
