Paper Abstract

A fiber refractive index sensor based on porous alumina is fabricated by pasting porous alumina film with 42.36μm on single mode fiber tip using the UV-cured adhesive. Experimental results show that the proposed sensor has a very high correlation with glycerine concentration (0.0%~80.0%) with correlation coefficient of 99.771%. Its sensitivity and resolution was measure to be 99.771%, 154 nm/RIU and 1×10-4 respectively when the refractive index changes from 1.333 to 1.443.
