Abstract :
Spatially resolved dispersion mapping of dispersion flattened highly nonlinear fiber (DF-HNLF) is reported. The characterization of a nearly dispersionless fiber-type is achieved through a generalized counter-colliding pulse method originally developed for conventional, linear-slope HNLF type. A new algorithm is developed in conjunction with the technique and applied to a 160-m-long DF-HNLF segment. The new method is used to identify the fiber part with largest dispersion fluctuations. A combined ability to spatially resolve DF-HNLF type and measure them with high accuracy carries a large practical importance for wideband mixer construction that requires precise phase matching conditions.
