摘要
利用耦合模理论分析了双芯光纤(TCF)的耦合特性与其结构参数的关系。结果表明,不同结构双芯光纤可能具有相同的耦合特性,从而可以根据实际应用对双芯光纤参数进行优化。同时提出一种改进型的双芯光纤制作工艺,采用化学气相沉积(MCVD)和光子晶体堆积工艺制作出均匀性良好的双芯光纤并对其参数进行了测量。
Abstract
The relation between coupling characteristic and numerical parameter of twin-core fiber (TCF) was analyzed with coupling mode theory. It’s proposed that the coupling characteristic of two different twin-core fibers can be the same so that the parameter of twin-core fibers can be optimized according to their application. Meanwhile,an improved fabrication method of twin-core fiber was presented. Twin-core fiber was fabricated by modified chemical vapor deposition (MCVD) and photonic crystal technology. Then,its numerical parameter was measured.
