摘要
Experimental results of noise characteristics of Er3+−doped optical fiber amplifiers, pumped by 0.98 and 1.48 μm LD's, are reported. The noise figures estimated from the beat noise between signal and spontaneous emission are 3.2 dB for pumping by 0.98 μ m LD and 4.1 dB for pumping by 1.48 μm LD. The beat noise between spontaneous emission components and the spontaneous shot noise for the 0.98 μm pumping are lower than those for the 1.48 μm pumping. © 1990 IEEE
