摘要
扩大传输容量已然成为现代光通信技术发展的首要任务。2μm波段属于人眼波段,并具有大气通信窗口,是未来光通信系统亟待开发的领域。软玻璃材料相比于石英玻璃,具有更宽的透光范围,并且可扩展到中红外波段,恰好配合2μm波段光通信系统。空芯光子带隙光纤(hollow core photonic bandgap fiber,HC-PBGF)由于光纤带隙的存在,提供了独一无二的导光模式。HC-PBGF具备灵活的光纤结构、较低的损耗,可控的色散特性,是非常适合光通信的传输媒介。设计了一种7-cell HC-PBGF,对该光纤的色散、模场面积、限制损耗和弯曲损耗等特性进行仿真分析。
Expanding transmission capacity has become the primary task for the development of modern optical communication technologies. The 2 μm band belongs to the human eye band and has an atmospheric communication window, which is an area in which optical communication systems need to be developed in the future. Compared with quartz glass, soft glass material has a wider light transmission range and can be extended to the mid-infrared band, which is suitable for the 2 μm band optical communication system. Hollow core photonic bandgap Fiber(HC-PBGF) provides a unique light guide mode due to the existence of fiber bandgap. HC-PBGF has a flexible fiber structure, low loss and controllable dispersion characteristics. It is a very suitable transmission medium for optical communication. A 7-cell HC-PBGF is designed, and the characteristics of dispersion, mode field area, limiting loss and bending loss of the fiber are simulated and analyzed.
