Abstract

We have fabricated a new type of dual-core fiber with two cores, one of which is made of silica and the other of which is made of a liquid with a higher refractive index than silica injected into a cylindrical cavity with a certain length in a single mode fiber. Thus, we have found a feasibility of a new type of temperature sensor in which the dependence of the refractive index of this liquid on temperature is combined with the optical coupling phenomenon in the conventional dual-core fiber. This paper reports our theoretical and experimental examinations on the feasibility of a dual-core silica fiber with a liquid core as temperature sensors.
