A novel intensity modulated fiber optic sensor (FOS) for liquid refractive index measurement is presented in this communication. The sensor principle is based on frustrated total internal reflection effect caused by refractive index change of a medium surrounding an optical fiber tip. Experimental r

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 t
## 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 lowβdispersion chrom
