采用纯硅光子带隙引导光纤作为材料沉积的三维模板，设计并制备了硅微结构光纤。由此产生的硅光纤具有微米大小的芯，但具有较小的芯包层指数对比，因此它只支持两个引导模式。结果表明，通过使用微结构模板，该纤维显示出许多与更传统的指数导向空气-二氧化硅结构相似的导向特性。硅微结构光纤的模式面积大，光损耗低，证明了其与现有光纤基础设施集成的潜力。
A silicon microstructured fiber has been designed and fabricated using a pure silica photonic bandgap guiding fiber as a 3D template for materials deposition. The resulting silicon fiber has a micron sized core but with a small core-cladding index contrast so that it only supports two guided modes. It will be shown that by using the microstructured template this fiber exhibits a number of similar guiding properties to the more traditional index guiding air-silica structures. The large mode areas and low optical losses measured for the silicon microstructured fiber demonstrate its potential to be integrated with existing fiber infrastructures.
