Abstract :
Differential stress distribution in a fused cross-sectional area of a polarisation-holding fibre coupler has been measured by using a Senarmont compensator. The stress profile is found to be effective for holding linear polarisations through the coupling region, i.e. the maximum stress difference is induced in the core region for the fibre coupler.
