Abstract

In this paper, we demonstrate a novel all-fiber current sensor using ordinary silica fiber and the fiber loop architecture that can be used to improve current sensitivity. In order to improve the efficiency of the sensor and reduce cost, we present a multichannel all-fiber current sensor based on the principle of time-division multiplexing. To illustrate the principle, we show the typical dual-channel all-fiber current sensor in our experiment. It shows that the currents at two different points can be measured simultaneously. In addition, we find by measurement that the dual-channel fiber current sensor has good linear responses dependence of the variation of the degree of polarization ∆P on the current intensity I for two channels respectively. Every channel is affected by the current alone, requires a separate calibration.
