The chromatic dispersion of an optical component is measured with high accuracy using a simple set-up, which includes a pump light source, a probe light source, and a measuring means. Pump light having a wavelength » pump and probe light having a wavelength » probe is propagated through an optical component, with the wavelength » probe being apart from the wavelength » pump by a given frequency. The generation efficiency of the idler light with respect to the wavelength » pump is calculated by measuring the power of idler light having a wavelength » idler output from the optical component, and by seeking the pump light wavelength for making the generation efficiency a local extreme value, the chromatic dispersion of the optical component is calculated from the result of calculation of phase mismatch among the pump light wavelength having such wavelength as sought, the corresponding probe light wavelength, and the corresponding the idler light wavelength. |
