摘要
掺铒光纤主要用来制作掺铒光纤放大器(EDFA)和掺铒光纤宽带光源(EDFS),在制作工艺上有液相掺杂、气相掺杂和螯合物掺杂,鉴于国内现有的设备条件和技术,近年来在研制掺铒光纤的过程中,采用了传统的液相掺杂制作工艺,但对其进行了大胆的改进和优化,在掺铒光纤制作工艺上取得了重大进展,光纤参数明显提高,与国外的同类型光纤比较,差距大幅度缩小,主要参数已达到或接近国外同类型掺铒光纤水平,本底损耗达到3.74dB/km,数值孔径为0.236,980nm吸收损耗达到6.05dB/m,在相当程度上已能够满足国内掺铒光纤放大器和掺铒光纤宽带光源研制单位对掺铒光纤的需要。
The Er^3＋-doped optical fiber is mainly used to make EDFA （Er^3＋ ＋doped optical fiber amplifier） and EDFS （Er^3＋doped optical fiber wide band light source）. There are liquid, gas and chelate doping techniques. Constrainted by the present domestic equipment and technical condition, the traditional liquid doping technique was adopted to manufacture the Er^3＋doped optical fiber in recent years by the 46th Institute. Through our bold trials to improve and optimize the technique, the great progress had been made so that the parameters of the manufactured fiber were enhanced obviously and could be compared with the same type fiber of foreign company. The difference betweem them is greatly narrowed, and the main parameters reach or approach to that of the foreign fiber of the same type. The background loss of manufactured fiber is 3.74 dB/km,its numerical aperture 0.236, the absorption loss at wavelength of 980 nm 6.05 dB/m.To some extent,the manufactured fiber can meet the domestic need for the development of EDFA and EDFS.
