耦合模式全光纤偏振模色散传递标准研制CSCD

偏振模色散（PMD）是发展高速光纤通信必须解决的关键技术之一,由于其具有很强的统计特性,很难对偏振模色散测试仪进行精确校准.波片堆作为理想的耦合模式偏振模色散传递标准已被许多著名校准机构采用,但由于其制作难度大、成本昂贵等特点,严重阻碍了其应用推广.介绍一种制作简单、成本低廉的全光纤耦合模式偏振模色散传递标准的制作方法,其稳定性为0.5％,与波片堆传递标准性能相当,优于普通光纤传递标准1～2个量级.

Mode-Coupled All-Fiber Transfer Standard Manufacture for Polarization Mode Dispersion

Polarization mode dispersion （PMD） is one of the key problems that must be solved for developing the high-speed fiber communication. It is difficult to calibrate PMD measurement instruments accurately because of the remarkable statistical characteristic of the PMD. As an ideal mode-coupled transfer standard, the wave-plate stack has been applied by many famous organizations. But it is difficult to manufacture the wave-plate stack, besides, it＇ s also very expensive. These factors form the block of the applications and popularizations of the wave-plate stack. We propose a method on the fabrication of an all-fiber mode-coupled transfer standard in this paper. The stability of this transfer standard is 0.5% , which is comparable with the wave-plate stack. This stability is 1 - 2 orders＇ higher than the ordinary fi- ber transfer standard. In addition, it is also easily realized and has the advantage of low cost.
