应用耦合模理论，首次计算了980urn／1550nm和1480urn／1550nm波分复用器港特性对掺饵光纤后向型超荧光激光器输出话线的影响作用，发现前者的影响作用不大，而后者则有明显的影响作用，其加权平均波长的差别可达2．3nm.
The coupled mode theory was used to calculate the influence of 980urn / 1550nm and 1480urn / 1550nm wavelength multiplexer ports on the output line of the erbium-doped back-type superfluorescent lasers. It was found that the effect of the former was not significant while the latter Have a significant impact, the difference between the weighted average wavelength up to 2.3nm.
