High efficiency parametric fiber devices are used for frequency generation, band-invariant amplification and general signal processing. Present generation of high-confinement fibers used for mixer design posses transverse variation control measured in silica molecular diameters, a critical feature for long-scale phase matching. We introduce new energy delivery method based localized four-photon mixing in order to achieve dispersion mapping of arbitrary dispersion fibers. The technique improves the sensitivity of existing dispersion mapping methods by orders of magnitude and is applicable to arbitrary waveguide type. Implications of the new technique is illustrated on general mixer applications.
