提出了一种适用于波分复用和多输入多输出（MIMO）组合传输系统的具有最小DMD斜率的双模光纤（TMF）。我们设计并制作了三种不同类型的半导体器件，即近零DMD（znD）、正DMD（pnD）和负DMD（nD），它们具有渐变折射率纤芯和凹陷内包层。我们证实了所制备的znxO 2在C波段的DMD小于15 ps/km，并且所制备的pnxO 2和nxO 2具有相同程度的有效面积。我们还证实了一条长度为100 km的由pn 2和nn 3组成的DMD补偿线可以成功地实现C + L波段的低DMD和低模式转换的最佳特性。
We propose two mode optical fibers (TMFs) with minimally low differential modal delay (DMD) slope which are suitable for wavelength division multiplexing and multiple input multiple output (MIMO) combined transmission system. We designed and fabricated three different kinds of TMF, nearly zero-DMD (zTMF), positive-DMD (pTMF) and negative-DMD (nTMF) with a graded index core and a depressed inner cladding. We confirmed that the fabricated zTMF has DMD of below 15 ps/km in the C band and the fabricated pTMF and nTMF have the same degree of effective areas. We also confirmed that a DMD compensation line with a length of 100 km composed of pTMF and nTMF can successfully achieve the best properties of low DMD in the C + L band and low mode conversion.
