Arrangement of fiber pieces for a wide wavelength conversion range by fiber four-wave mixing.
A new technique is reported for obtaining a wide wavelength conversion range in fiber four-wave mixing. One fiber is cut into short fiber pieces and rearranged, considering the zero-dispersion wavelength of each fiber piece. With this rearrangement, the wavelength conversion range is expanded, compared with that in the original fiber. An experiment using a 6-km fiber confirms the technique.
