Abstract :
A simple and accurate method is devised to calculate the geometric birefringence of optical fibres with asymmetric claddings. The method gives analytical results near the cutoff or transition frequencies of the guided modes. It is found that some asymmetric claddings cannot be used to introduce birefringence effects near the cutoff or transition frequencies.
