摘要
We propose a novel optical bistable device （OBD） in frequency-domain with which we can perform optical bistable operations in a number of fibre Bragg gratings （FBGs） which are included in the same OBD. Such an OBD may bring more opportunities in applications and, as an example, we show the possibility of using it in an FBG sensor demodulating system. By use of a tunable light source, consisting of a broad band source and a scanning fibre F-P （FFP）, we demonstrate the above-mentioned operations experimentally.
