Abstract

We demonstrate a novel method for low-loss splicing small-core photonic crystal fibers (PCFs) and single-mode fibers (SMFs) by repeated arc discharges using a conventional fusion splicer. An optimum mode field match at the interface of PCF-SMF and an adiabatic mode field variation in the longitudinal direction of the small-core PCF can be achieved by repeated arc discharges applied over the splicing joint to gradually collapse the air holes of the small-core PCF. This method is simple and offers a practical solution for light coupling between small-core PCFs and SMFs.

摘要

我们展示了一种通过使用传统熔接机进行重复电弧放电来实现小芯光子晶体光纤（PCF）与单模光纤（SMF）低损耗熔接的新方法。通过在熔接接头处施加重复电弧放电，使小芯PCF的气孔逐渐塌陷，可在PCF-SMF界面实现最佳模场匹配，并在小芯PCF的纵向实现绝热模场变化。该方法简单，为小芯PCF与SMF之间的光耦合提供了一种实用的解决方案。
