Abstract

An intrinsic refractive index sensor has been developed based on Fresnel reflection at the interface between the single mode fiber core and a cap material. The sensor is capable of measuring the refractive index of the cap material and can be applied to temperature, pressure, and magnetic and electric field sensing. Suitable cap materials may be chosen which have a birefringent response to mechanical stress, thermal stress, electric fields, or magnetic fields. A temperature sensor application characterizes the technique using cap materials of carbon tetrachloride, toluene, and dodecane.
