| contents | We propose and study a method for measuring the chromatic dispersion parameter (D) of optical fibers and bulk optical elements through the use of a single-arm three-wave interferometer and a fiber femtosecond frequency comb (FFFC). The FFFC is frequency locked to a single-ytterbium-ion optical standard and employed as a source of highly stable and broadband laser radiation. The FFFC spectrum ranges from 1 to 2 microns, which is the most demanded range in fiber optics. The theoretical model presented in the work is used to derive analytical expressions for the parameter D, taking into account the second-order group velocity dispersion. To validate the methodology, the parameter D is measured for a standard single-mode SMF-28 fiber. The proposed method enables the precise measurement of the parameter D with high accuracy across a broad spectral range in a relatively short time. |
