Abstract
This paper reports on results with a novel Sagnac-loop sensor, using spectral slicing of a broadband Er-doped fibre source and has a 40km long sensor loop. Our new WDM arrangement allows use of a single source and optical receiver, yet has low intrinsic losses. The residual optical crosstalk due to non-ideal WDM components is modelled and the initial position dependent results presented.
