Abstract: A numerical study of self-sustained mode locking due to optically induced nonlinear birefringence is presented. The model incorporates a polarizer, a gain medium, a half-wave plate and a single-mode passive fibre in a ring cavity configuration. The mechanism exploits polarization instability in optical fibre with a weak, linear, intrinsic birefringence.
