|摘要:||A new technique, using chirped fiber gratings (CFGs) with different dispersions and center frequencies to reflect the different channel pulses at different positions, is proposed to compensate for the accumulated dispersions and flatten the signal gain of the erbium-doped fiber amplifier (EDFA) in a wavelength division multiplexing (WDM) system. A numerical example of the gain flattened and dispersion compensation for four channel multiplexed signals in the 1544-1556 nm wavelength region is shown. (C) 1999 Elsevier Science B.V.
