The stress distribution in an optical fiber with single stress element is calculated and analyzed. The stress oscillation magnitudes related to mode coupling are characterized. The coupling ability between the fundamental mode HE11 and other modes is demonstrated and compared. The strongest coupling is occurred between the fundamental modes HE11+andHE11-. The coupling strength fromHE11-HE21, HE11-HE22, HE11-HE31, HE11-HE41, HE11-HE12 and HE11-HE51 is decreased in turn. Possible coupling between the fundamental mode HE11 and other higher order modes is much smaller and can be ignored.

单应力元件光纤的耦合能力比较

计算并分析了具有单个应力元素的光纤中的应力分布。表征了与模式耦合有关的应力振荡幅度。基本模式之间的耦合能力HE11和其他模式进行了演示和比较。基本模式之间发生最强的耦合HE11+HE11--。耦合强度从HE11--HE21岁HE11--HE22HE11--HE31HE11--HE41HE11--HE12HE11--HE51依次减少。基本模式之间可能的耦合HE11 和其他高阶模式要小得多,可以忽略不计。
