Abstract :
A new technique, using fibre-Bragg gratings with different centre frequencies to reflect the different channel signals at different positions, is proposed for flattening the gain spectrum of an erbium-doped fibre amplifier. A designed gain excursion of <0.1 dB can be achieved for 16 channel multiplexed signals with 0.1 mW input power in the 1532-1562 nm wavelength region
