dc.description.abstractThe coupling of Rayleigh backscatter induced phase noise in bi-directional, inline fiber interferometers compromises detection sensitivity for Fourier frequencies less than 1 Hz. Here we report experimental and theoretical work highlighting the coupling of backscatter phase noise, and its subsequent range-gating and suppression using digitally enhanced homodyne interferometry. Between two in-line fiber interferometers, each with a differential arm-length of 8 km, we demonstrate a relative stability of 10 Hz/√Hz at a Fourier frequency of 100 mHz.en_AU
