title: Cascaded four-wave mixing seeded by two continuous wave signals.
abstract: We report on the broadband-cascaded four-wave mixing (CFWM) products generated in a photonic crystal fiber pumped by a picosecond pulse and seeded by two continuous wave (CW) signals. The equal and unequal frequency spaced CFWM products could be obtained through continuously tuning one of the CW wavelengths. Among the equally spaced CFWM products, the smallest frequency spacing was 477 GHz. The influences of the Raman scattering and the third-order dispersion on the CFWM were also discussed.
