摘要
The present invention relates to a method and devices that make use of transmission edge filters based on apodized linearly chirped (LC) fiber Bragg gratings (FBGs) to provide the variable attenuation required for power equalization among different wavelength channels in an erbium-doped fiber amplifier. This approach is especially attractive since it can easily be extended to provide dynamic power equalization by simply incorporating a feedback loop.
