摘要:
An optical fiber preform, and method for fabricating, having a first core, a second core spaced from the first core and first and second regions, the first region having an outer perimeter having a first substantially straight length and the second region having an outer perimeter having a second substantially straight length facing the first straight length. One of the regions can comprise the first core and the other comprises the second core. The preform can be drawn with rotation to provide a fiber wherein a first core of the fiber is multimode at a selected wavelength of operation and a second core of the fiber is spaced from and winds around the first core and has a selected longitudinal pitch. The second core of the fiber can couple to a higher order mode of the first core and increase the attenuation thereof.
摘要(中):
一种光纤预制件及其制造方法,具有第一芯体,与第一芯体以及第一和第二区域隔开的第二芯体,第一区域具有第一基本上直的长度的外周边,第二区域具有外周边 具有面向第一直线长度的第二基本上直的长度。 其中一个区域可以包括第一核心,另一个包括第二核心。 预成型件可以旋转拉伸以提供纤维,其中纤维的第一纤芯在所选波长的操作下是多模的,并且纤维的第二纤芯与第一纤芯间隔开并卷绕第一纤芯并具有选定的纵向间距。 光纤的第二个核心可以耦合到第一个核心的高阶模式并增加其衰减。
