Abstract
A variable gain tilting filter (VGTF) for dynamic gain flattening of erbium-doped fiber amplifiers (EDFAs) is proposed based on PMN-PT, a transparent ceramic material with high electro-optic coefficient. The electro-optic coefficient of PMNPT is measured and a VGTF is assembled. The device is tuned in in phase and amplitude, respectively. The measured spectrum match well with theoretical simulation.
