掺铒光纤最佳长度

The Optimum Length of Er^(3+)-Doped Fiber

根据掺铒光纤放大器的理论模型,得到了掺铒光纤最佳长度数学表达式,并根据此表达式,通过对掺铒光纤衰耗的测量,可从理论上计算掺铒光纤最佳长度。计算结果同实验值非常吻合。由此,得到一种非常简单、可靠的确定掺铒光纤最佳长度的理论方法。

The mathematics expression of Er^(3+)-doped fiber optimum length from the theoretical model of EDFA are given. According to the expression, we can calculate the optimum length of Er^(3+)-doped fibers by the loss measure. The optimum length is found to be in excellent agree with the result of the experiment. So, we have a very simple, reliable method to decide the optimum length of Er^(3+)-doped fibers.
