| 摘 要： | 报道了一种新型980 nm激光二极管(LD)泵浦高增益的掺铒光纤放大器(EDFA).通过加入中心波长为1 550 nm光纤光栅(FBG)可以明显提高增益,并分析了增益钳制的原理.实验得到其增益比无FBG结构EDFA提高8 dB,并得到了小信号输入时增益25 dB的有效钳制.

| Abstract: | A novel Erbium-doped fiber amplifier(EDFA) pumped by 980 nm LD that improves the L-band amplification performances is demonstrated.By utilizing fiber Bragg grating(FBG) with a center wavelength of 1550 nm,the gain is improved obviously.The principle of gain-clamping has been analysed.Experimental results show the signal gain is enhanced by the FBG more than 8 dB.The amplifier gain is clamped at 25 dB with a gain variation of less than 0.5 dB for input power as high as(-15 dBm.) |
