Abstract :
Remarkably simple, analytical expressions are presented for the calculation of the birefringence in stress-applied polarisation-maintaining optical fibres. The method is based on the vector analysis of propagation constants in dielectric waveguides with perturbed refractive-index profile. It is shown that present results agree well with the results obtained using the finite-element method.
