Dynamic gain equalization system design with adaptive spectrum decomposition methodology |
摘要 |
The present invention discloses an optical gain equalization system for receiving and equalizing a multiple-channel input optical signal. The optical gain equalization system includes a cascaded array of tunable optical filters filtering the multiple-channel input optical signal and generating a plurality of sub-signals and a residual signal and each of the sub-signals transmitted over a mutually exclusive filter-specific spectrum-range while a combination of all the filter-specific spectrums dynamically covering the spectral portions of said multi-channel input optical signal where power equalizations are required, and all said filter-specific spectrums together with the residual signal spectrum substantially covering an entire spectral range of the multi-channel input optical signal. The gain equalization system further includes a corresponding array of variable optical attenuators (VOAs) each connected to one of a corresponding tunable optical filter for attenuating the sub-signal transmitted over the filter-specific spectrum range for generating an equalized sub-signal. And, the gain equalization system further includes a multiplexing means for receiving and multiplexing the equalized sub-signals generated by the array of variable optical attenuators (VOAs) and the residual signal for generating an equalized output optical signal.
