Abstract
A dynamic gain equalizer (DGE) for an optical communication device and related method which are capable of reducing power variations among wavelength division multiplexing (WDM) signals. The DGE and method use an optical attenuation device configured such that the ratio of pixel gap distance to the channel beam diameter at the point of incident to the optical attenuation device is less than or equal to 0.06. The DGE can produce output signal sets that have ripple increases of less than 0.1 db over the input signal sets.
