利用1.47 μm及1.45 μm半导体激光器泵浦的掺铒光纤放大器进行了实验研究。结果表明,用1.45 μm半导体激光器泵浦掺铒光纤也能对信号光放大。用1.45 μm和1.47 μm半导体激光器双向泵浦掺铒光纤,获得了27 dB的增益。

In this paper, the Er3+-doped optical fiber amplifiers (EDFA's) have been investigated experimentally, which are pumped by LDs at wavelengths of 1.45 μm and 1.47 μm. The results show that the signal light can also be amplified by the EDFA pumped at wavelength of 1.45 μm. A gain of 27 dB has been obtained for the EDFA's forwards and backwards pumped at wavelengths of 1.45 μm and 1.47 μm.
