Abstract :
The influence of the degree of fusion on the form birefringence of fused optical fibre couplers is investigated based on a rigorous vectorial analysis using the surface integral equations method. Form birefringence against aspect ratio of the coupler cross-section for different normalised frequencies V are calculated. It is found that the birefringence is also significant as the degree of fusion approaches 2.0
