Backscatter-immune, polarization managed, all fiber Sagnac sensing interferometer

Chow, Jong; McClelland, David; Gray, Malcolm B


We propose a new all fiber Mach-Zehnder-Sagnac hybrid interferometer topology for precision sensing. This configuration utilizes a high coherence laser source, mitigates the effects of Rayleigh backscatter and polarization wander, while eliminating scale factor drift. We also present preliminary experimental results, using telecommunications grade single mode fiber and fiber couplers, to demonstrate its principle of operation.
