| 摘 要： | 采用后向泵浦方式，利用波长分别为1426，l440，1454，1472及1496nm的大功率半导体激光器作为泵源，实现了带宽为80．nm(1530～1610nm)的宽带分布式拉曼光纤放大器，对40个信道的信号进行分布式放大，获得了较好的增益平坦及噪声特性．信号经60km的普通单模光纤传输后，平均开关增益为16．5dB，增益平坦度为1.5dB，最大等效噪声指数为-0．9dB．采用Agilent 8166B测试系统的多通道信号源(C L-band)作为信号源测量增益谱．由于考虑了信号光之间的相互拉曼作用及信号光对泵浦的影响，实验结果更精确．

| Abstract: | Using 5 high power laser diodes at 1 426,1 440,1 454,1 472 and 1 496 nm,respectively,as the multi-pumps,a wideband distributed Raman fiber amplifier ( 1 530 to 1 610 nm) was obtained based on backward pump scheme,which was tested by amplifying 40 signal channels. After transmitting 60 km standard single-mode fiber (SSMF),signals have acquired an average on-off gain of 16.5 dB and a gain flatness of 1.5 dB. The maximum effective noise figure (ENF) is -0.9 dB . The multi-channel signal source in Agilent 8166B test system was used to measure the gain spectrum. Since the signal-to-signal Raman interaction and the influence on pump caused by signal are considered,the experimental results are more accurate. |
