Phase matching the stimulated four-photon mixing process on single-mode fibers operating in the 1.55-microm region

Phase matching the stimulated four-photon mixing process on single-mode fibers reveals information about the dispersion properties of the fiber, in particular, the zero-dispersion wavelength. Examples of the expected frequency-shift behavior around the zero-dispersion wavelength are given for multiply clad silica glass single-mode fibers designed for minimum dispersion operation in the 1.55-microm region.
