Adjustable EDFA Gain Equalization Filter Based on a Single LPG Excited by Flexural Acoustic Waves for Future DWDM Networks

abstract

A fast adjustable EDFA gain equalization filter for DWDM system is reported. Using an LPG which is excited by means of flexural waves, the equalization with a gain flatness <0.3dB is demonstrated, inducing a power penalty <0.84dB. © 2012 OSA - The Optical Society. All rights reserved.
