Description

新型光放大器
本发明是新型光放大器。
近年来,信息通信产业以人们难以想象相象的速度飞速发展。信息传输量爆炸式扩大。目前所用的光纤网已经不能满足信息通信产业飞速发展的需要。特别是密集波分复用(DWDM)技术的使用后,这个矛盾更加突出。对整个光纤网,特别是对光纤网中的光放大器要求更高。
本发明的目的就是提供一种新型光放大器,通过改变传统光纤放大器的结构,提高掺铒光纤的效率,使器件小型化。
本发明的新型光放大器,其特征是用多光源激起替代传统的单一光源。
如上所述的新型光放大器,其特征是所有连接处均采用低损耗V型槽斜面连接,掺铒光纤直一端与波分复用器连接,另一端与光隔离器连接。
使用多光源激起替代传统的单一光源激起,提高掺铒光纤的效率,减少掺铒光纤的长度,采用低损耗V型槽斜面连接,省去传统光纤放大器中的一些为减少连接损耗用的石英连接光纤,使光放大器小型化,效率化。
图1,是传统掺铒光纤放大器结构示意图。其中,1信号,2光隔离器,3波分复用器,41波长半导体光纤激光器,5掺铒光纤,6光隔离器,7信号检测器,8、9石英光纤。
图2,是本实用新型光放大器的实施例的结构示意图。其中,1信号,2光隔离器,3波分复用器,4波长半导体光纤激光器,5掺铒光纤,6光隔离器,7信号检测器。
图3,是图2实施例的杂音信号。
图4,是图2实施例的信号增益。
为了更好地阐述该发明的成效,我们列举实施例如下:
光放大器结构参见图2。将50cm长掺铒重金属氧化物玻璃光纤5,808nm,980nm半导体光纤激光器4,光隔离器2,波分复用器3组成为光放大器,光纤5的比折射率差为1.5%。截止(Cut Off)波长960nm。所有的连结处都光学抛光成斜面并用光学粘结剂在V型槽中固定以减少光损失。用150mW半导体光纤激光器4激起时,从1525nm到1630nm广域波长内得到24dB的平坦信号放大。信号增益见图3。偏差为2dB,噪音信号小于5dB。杂音信号见图4。
