1480 nm LD泵浦掺铒光纤放大器的增益带宽特性的研究
Study on Gain and Bandwidth Characteristicsof 1480 nm LD Pumped EDFA Module
摘要
采用国产1480 nm LD及优化的掺铒光纤,研制成光纤增益达32 dB、最大输出功率为10 dBm、带宽大于25 nm的掺铒光纤放大器模块(其纤入纤出净增益为27 dB、输出功率为7 dBm)。讨论了放大器的增益、带宽特性及ASE对放大器测量的影响。
Abstract
A co-pumped Erbium-Doped Fiber Amplifier (EDFA) which consists of home-made 1480 nm pigitaled LD's and erbium doped fiber (EDF) has been developed. A small-signal gain of 32 dB of the EDFA has been obtained (fiber to fiber net gain is 27 dB). The saturation power and maximum power of fiber are 2.5 dBm and 10 dBm, respectively, while the gain bandwidth is greater than 25 nm.The gain and bandwidth characteristics of the EDFA are studied. Effects of Amplified Spontenous Emission (ASE) on measurement are discussed.
