我们介绍了一种通用的，强大的，和集成的技术，选择性地填充流体到所需的模式的空气孔的光子晶体光纤（PCF）。聚焦离子束（FIB）用于在PCF的端面上高效地铣削微通道，然后将其拼接到单模光纤（SMF）。因此，选定的气孔通过微通道暴露于大气中，用于流体填充。利用这种技术实现了一种低损耗的同轴可调谐混合光纤器件。
We introduce a versatile, robust, and integrated technique to selectively fill fluid into a desired pattern of air holes in a photonic crystal fiber (PCF). Focused ion beam (FIB) is used to efficiently mill a microchannel on the end facet of a PCF before it is spliced to a single-mode fiber (SMF). Selected air holes are therefore exposed to the atmosphere through the microchannel for fluid filling. A low-loss in-line tunable optical hybrid fiber device is demonstrated by using such a technique.
