A polarization switching and Faraday rotator mirror hybrid method for ultra-low polarization fading noise in optical fiber hydrophone
We present a polarization switching(PS) and Faraday rotator mirror (FRM)hybrid method to comprehensively suppress polarization fading induced noise in optical fiber hydrophones. Compared to the widely used FRM method, the introduction of PS brings an additional 10.5 dB phase noise reduction, which can significantly reduce the minimum measurable underwater signal.
