DisplayPort数据线以其高速度、超宽带、低成本为广大终端PC及EC生产厂家所支持,传统的基于铜缆的数据线在用于生产这种新型数据传输线时面临着局限,而基于光缆的Dispalyport显视出巨大应用空间。本文主要论述了一种能从根本上增大单模光纤芯径的方法,首先简单介绍了增益导引效应的原理,重点对纤芯径向折射率平方律变化的光纤中的模式进行了分析,并得出了这种新型光纤中单模传输的数值解。结果表明:使用增益导引技术,突破了在传统的折射率导引下,保持单模大模场面积输出所面临的困境,结果显示这种新型光纤在单模传输时的纤芯直径相对于常规的折射率导引有两个数量级的提高,并指出了对增益导引光纤的广泛的应用前景。
DisplayPort data lines are supported by the majority of terminal PCs and EC manufacturers for their high speed, ultra-wideband, and low cost. Conventional copper-based data lines face limitations when used to produce this new type of data transmission line. Dispalyport shows a huge application space. This paper mainly discusses a method that can fundamentally increase the core diameter of single-mode fiber. Firstly, the principle of gain-guided effect is briefly introduced, and the mode of fiber with the square-law of core radial refractive index is analyzed The numerical solution of single mode transmission in this new type of optical fiber is obtained. The results show that the use of gain guidance technology, breaking through the traditional index of refraction, to maintain the single mode large mode field output of the difficulties faced by the results show that the new optical fiber in the single mode transmission core diameter relative to Conventional refractive index guidance has two orders of magnitude improvement and points to a wide range of application prospects for gain guided fiber.
