Abstract :
To suppress the undesirable sideband transmission occurring in the conventional fibre Bragg grating based Fabry-Pérot filter, a fibre Fabry-Pérot interferometer that is composed of a single fibre Bragg grating and a broadband high-reflectance dielectric mirror coated on a fibre end surface is considered and its very narrow transmission bandwidth of 8.8 pm and high sideband suppression ratio of more than 20 is experimentally demonstrated in good conformity with the numerical simulation.
