Abstract

Simultaneous measurements of refractive index (RI) and temperature are proposed and experimentally demonstrated by using a tapered bend-resistant fiber interferometer. Different phase shifts of an inner and outer cladding mode of the fiber interferometer are measured to determine the temperature compensated RI of a glycerol solution. The temperature coefficients of the inner and outer cladding modes are 0.0253 rad / ° C and 0.0523 rad / ° C , and the RI coefficients are 4.0403 rad / R I U and 44.823 rad / RIU , respectively. The minimum errors of temperature and RI are 0.6°C and 0.001 RIU, respectively.
