中文摘要:
以便完成更高光谱效率,在很少模式纤维的模式部门 multiplexing (MDM ) 是一个新研究区域。这个想法包括联合限制系统的可完成的长度的 intermodal 延期和模式面对大量技术问题。这篇论文被指定在步索引很少模式纤维完成 intermodal 延期的分析。我们数字地分析纤维的所有参数,它能在很少模式纤维影响 intermodal 延期并且识别没有最大的 intermodal 延期的重要增加,能增加复合模式的数字的条件。
英文摘要:
In order to achieve higher spectral efficiency, mode division multiplexing (MDM) in few-mode fibers is a new research area. The idea faces lots of technical issues including intermodal delay and mode coupling which limit the achievable length of the system. This paper is designated to complete the analysis of intermodal delay in step-index few-mode fibers. We analyze numerically all the parameters of fiber, which could impact intermodal delay in few-mode fibers and identify the conditions which can increase the number of multiplex modes without significant increase in maximum intermodal delay.
