Frequency shifter and polarisation controller based on birefringence of bending ordinary single-mode fibre
A frequency shifter and a polarisation controller are described in this paper, which are based on birefringence induced by bending ordinary single-mode fibre. 30 dB suppression of the unwanted sideband has been achieved in the frequency shifter. Two fibre devices can be used in functional optical fibre sensors as aa attractive fibre devices for whole fibre sensors.
