Gain flattened L-band EDFA based on upgraded C-band EDFA using forward ASE pumping in an EDF section
, 2000 A novel method is presented for implementing an L-band erbium doped fibre amplifier (EDFA) making use of forward amplified spontaneous emission pumping, from a commercially available c-band EDFA, in an erbium doped fibre.

Guangtongxin yanjiu, 1995 本文提出了掺铒光纤放大器（ＥＤＦＡ）增益的精确模型，并对ＥＤＦＡ的增益进行了计算，其结果与实验相当符合。并在此基础上，结合光子数的Ｍａｓｔｅｒ方程和Ｐｅｒｓｏｎｉｃｋ关于接收机的理论，详细地分析了当ＥＤＦＡ为前放、中继时，其增益与接收机的噪声以及灵敏度在一定误码率下的关系。

Highly saturated EDFA for gain clamping operation
, 2007 A highly saturated erbium-doped fiber amplifier (EDFA) that can be used for gain-clamping is demonstrated. This amplifier utilizes a short length of active fiber to provide a small but maximum gain and a high pump power to enhance the gain dynamic range.

Bi-Directionally-Pumped Few-Mode EDFA
, 2014 We present a model for the performance of bi-directionally-pumped few-mode EDFA for the first time. Bi-directionally pumping can realize the best trade-off among metrics important for SDM including gain, noise figure and power conversion ...
