Abstract

Fibre polarisers are essential devices in optical fibre communication and sensor systems whenever the control of polarisation is needed. They are particularly important in fibre-gyro systems where low insertion-loss and high extinction-ratio polarisers are requiredt^[1] . A wide polarising spectral-window is another important requirement, since in many practical fibre systems broad-spectrum LEDs are used as the light source. Wide-bandwidth polarisers are also needed in wavelength-multiplexing systems.
