  • Abstract
    In a `reciprocal architecture¿ FOG a single-mode filter is used to reduce bias drift resulting from changing fibre birefringence. We show that if a birefringent element is combined with this filter the bias is reduced if the dispersion in the element exceeds the source coherence length. This significantly relaxes the requirements for mode filter extinction.
