【摘要】 在拉曼光纤放大器理论建模的基础上,设计并制作了四波长八泵浦反向激励且带宽为90nm的光纤放大器。利用康宁公司生产的25kmSMF作为增益光纤,得到拉曼增益为(11.5±1)dB。采用在不同泵浦情况下实测得到的信号增益系数谱和泵浦之间的增益系数谱,使理论建模得到的拉曼增益与实测相一致。更多还原

【Abstract】 A fiber Raman amplifier with bandwidth of 90 nm using eight pump lasers was presented. Based on the theoretic model, a gain of (11.5±1) dB was obtained with the 25 km SMF manufactured by Corning Corp as gain media. The experimentally measured spectra of signal gain coefficient and inter-pump gain coefficient for different pump parameters are in good agreement with the results of improved theoretic model.更多还原
