A responsivity of 1.28 x 10-4 rad/I2 at 50Hz of current signal has been shown, with capability of measuring alternating current signals up to 500Hz.

Abstract

In this paper we demonstrate a compact current sensor using the optic fiber micro wire, based on the idea of interferometrically measuring the thermally induced optical phase shifts as a result of heat produced due to the flow of electric current over short transit lengths. A responsivity of 1.28 x 10-4 rad/I2 at 50Hz of current signal has been shown, with capability of measuring alternating current signals up to 500Hz.
