✦ Synopsis

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 results obtained for liquids of different refractive index confirm the sensor potential to act as a sensitive refractometer.

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

Design and operation of an optical ΓΏber device for temperature sensing and thermal expansion measurement are reported. The modulated intensity has been measured by using a pair of 450 m core ΓΏber, one acting as the source and the other one as receiving ΓΏber. In this design, the light intensity modul
