摘要
提出了一种新的光纤拉曼增益谱的测量方法,通过光纤的受激拉曼谱和自发辐射谱的解调而获得拉曼增益谱图,同时利用该方法用于3个波长为1428nm,1445nm,1467nm抽运的宽带光纤拉曼放大器的设计,得到最大开关增益13dB,1dB带宽34nm的拉曼放大,与小信号增益法测量结果一致。实际证明:该方法快速简单、实时性强,具有实际应用价值。
A new method was developed for measuring the fiber Raman gain spectrums,which is obtained by demodulation of the stimulated Raman spectrum and the spontaneous emission spectrum, this method is proved to have a good performance in the measurement of the fiber Raman gain spectrums, and three wavelength （ 1428nm, 1445nm, 1467nm） pump broadband Raman fiber amplifier with gain band over 34 nm（ 1 dB）, on-off gain of 13 dB is designed by this method, and the experimental result is agree with the measurement by the small signal gain method. The result of experiment show the way possesses simple performance ,high accuracy ,high good real-time characteristic and useful value.
