【Abstract】 Based on theory analysis, we have demonstrated experimentally how to use cascaded wideband fibre Bragg grattings (FBGs) as reflectors in the superfluorescent fibre sources (SFS) configuration. In the experiment, we investigated the output characteristcs of the set-up with cascaded wideband FBGs, and compared it with those of the set-up with fibre ring reflector or without any reflector. From what we have achieved in the experiment, we find that the cascaded wideband FBGs is promising to be used as reflectors in SFS.更多还原
