Abstract :
Endlessly rotatable fractional-wave devices for polarisation control in single-mode fibres are described which utilise stress birefringence induced by fibre bending, and are free from fibre twist by rotating the fibre around its own axis. Experiments confirm that these devices rotate endlessly and have small hysteresis.
