RESEARCH OF EDFA GAIN FLATTENING BASED ON CHIRPED FIBER BRAGG GRATING

摘要：

Erbium-doped fiber amplifier, with advantages of high gain, large bandwidth and low noise and disadvantages of uneven gain, is an important component in wavelength division multiplexing optical communication systems. This uneven characteristic will surely lead to reduced effective transmission bandwidth and system performance degradation. This paper studies on issues of EDFA gain flattering based on chirped fiber Bragg grating, and provides detailed analysis of the method of using chirped fiber bragg grating to achieve flat EDFA output gain. Numerical simulation result shows that this method can reduce unevenness to 0.2dB and below.
