title: Dynamic gain-tilt compensation using electronic variable optical attenuators and a thin film filter spectral tilt monitor.
abstract: An all-optical dynamic gain tilt compensator (DGTC) is proposed and experimentally demonstrated. A single wide-band thin film filter and a pair of photodetector allow the DGTC to distinguish band add/drop position. Power fluctuations from EDFA gain tilt were reduced with fast electronic variable optical attenuators.
