✦ Synopsis

A novel experimental technique for the measurement of the nonlinear refractive index coefficient, n 2 , based on the detection of self-phase modulation phase shift by means of an all-fiber Sagnac interferometer, is proposed. Measurements performed on dispersion-shifted fibers clearly indicate that the value of n 2 at 1550 nm is around 2.5 Γ— 10 -20 m 2 /W, considerably lower than in the visible wavelength range.

## Abstract The simultaneous measurement of the nonlinear refractive index and the chromatic dispersion measurement of dispersion shift fibers are proposed, based on the power determination of the mixing products generated by four pump waves. This method is also used with other low‐dispersion chrom
