Abstract :
Single-mode fibre recirculating delay lines have been made on a single continuous loop of fibre with the use of fibre directional couplers. These devices have been demonstrated as bandpass filters and as notch filters at centre frequencies from 0.5 MHz to 1.3 GHz with a notch depth of over 45 dB.
