title = "A novel optical fiber current sensor using polarization diversity and a Faraday rotation mirror cavity",
abstract = "A novel high sensitivity optical fiber current sensor (OFCS) based on polarization diversity (PD) and a Faraday rotation mirror cavity (FRMC) is proposed and demonstrated. The PD detection doubles the sensitivity and effectively removes the DC background compared with the single-channel detection, while the FRMC suppresses the reciprocal birefringence and amplifies non-reciprocal phase modulation caused by the current-induced magnetic field. Compared with the results obtained by single-channel detection, a signal gain of 6dB and a signal-to-noise ratio improvement of over 30dB have been achieved in the new scheme. A linear response is obtained for current amplitude as low as mA.",
