Abstract :
Polarisation characteristics of stress-applied polarisation maintaining fibres having graded-index cores with ¿-power profile are investigated. It is found that when the stress-applying parts approach the core, the dependence of modal birefringence B on the normalised frequency v for the triangular profile is considerably different from that for the step-index profile, and the absolutely single-mode operation can be easily realised compared with the conventional step-index profile.
