摘要： 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 λpump and probe light having a wavelength λprobe is propagated through an optical component, with the wavelength λprobe being apart from the wavelength λpump by a given frequency. The generation efficiency of the idler light with respect to the wavelength λpump is calculated by measuring the power of idler light having a wavelength λidler 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.

摘要： An optical fiber and an optical fiber device, which can suppress generation of the stimulated Brillouin scattering while maintaining large nonlinearity. The fiber includes a central core which is made of SiO2 as a main component and contains Al2O3 at concentration of 15 wt % or more. The fiber is allowed to propagate only a fundamental mode and has an absolute value of chromatic dispersion of 5 ps/nm/km or less at a predetermined wavelength. The device includes the fiber having the above composition. The fiber guides first light and second light having different wavelengths to propagate therethrough such that the first light and the second light interact with each other by a nonlinear optical phenomenon during the propagation, thus causing the fiber to output the first light or the second light modulated by the nonlinear optical phenomenon or third light newly produced by the nonlinear optical phenomenon and having a different wavelength.
