Abstract

We report a detailed study of the noise properties of dual Mach-Zehnder interferometers interrogated with narrowband (<15GHz) fiber ASE sources. A minimum detectable phase of 62 μrad/Hz1/2 is obtained for practical values (~1cm) of length mismatch using a simple heterodyne technique and optimized configuration.
