Abstract :
Two different methods are demonstrated for simultaneously monitoring multiple fibre gratings using a single acousto-optic tunable filter. One method demultiplexes signals from the gratings optically, and the other uses electronic processing. Crosstalk levels below -52 dB have been observed for both methods
