摘　　要：基于单个光纤光栅反射技术提出一种高性能L波段EDFA。用一个光纤布拉格光栅(FBG)反射EDFA产生的一部分C波段放大自发辐射(ASE)噪声,该部分ASE噪声被重新注入到掺铒光纤中以提高增益效率。用静态均衡器平坦输出的增益谱,在L波段范围内,增益被箝制在25.5dB,增益不平坦度小于0.5dB,噪声指数小于5.5dB,为DWDM系统提供了一项有效的解决方案。A gain enhanced L-band erbium-doped fiber amplifier (EDFA) using a single Fiber Bragg Grating is presented. Using a single regular fiber Bragg grating (FBG) injecting C-band ASE offering low-cost amplification and a static equalizer offering flatten gain ,the gain values of 27dB with less than 0.5dB gain variations over 35nm and NF<5. 5dB are obtained. The proposed EDFA provides a cost-efficient solution for wavelength division multiplexing system.
