Paper Abstract

A temperature independent microdisplacement sensor based on microbending-induced core-cladding mode coupling loss via a polarization maintaining photonic-crystal-fiber (PMPCF) is presented. By core-offsetting one splice joint between the single mode fiber (SMF) and PMPCF in an SMF-PMPCF-SMF structure, one core-cladding modal interferometer can be constructed. By packaging the interferometer in a carbon-fiber-composite based simple-supported beam, temperature independent microdisplacement measurement can be achieved by monitoring the extinction ratio variation of the interference spectrum. This type of sensor exhibits the advantages of temperature independent, high sensitivity and simple structure.
