Accurate measurements of the zero-dispersion wavelength in optical fibers

Abstract

We have developed a frequency-domain phase shift system for measuring the zerodispersion wavelength and the dispersion slope of single-mode optical fibers. A differential phase shift method and nonlinear four-wave mixing technique were also investigated. The frequency-domain phase shift method is used to produce Standard Reference Materials that have their zerodispersion wavelengths characterized with an expanded uncertainty (k = 2) of ± 0.060 nm.
