Paper Abstract

The authors report the experimental and theoretical study of a sensor based on the temperature induced by the variation of the refraction-index difference versus the temperature when PCS fiber is used. This sensor uses the fiber directly as temperature sensor, as well as to transmit data. Because of the sharp variation of bend losses under strong curvatures, it has a high sensitivity over a wide range.
