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.
一种硅微结构光纤已被设计并制造出来，它以纯二氧化硅光子带隙导波光纤作为材料沉积的三维模板。所得的硅光纤具有微米尺寸的纤芯，但纤芯与包层的折射率对比度较小，因此仅支持两种导模。结果表明，通过使用微结构模板，这种光纤展现出了许多与更传统的折射率导光型空气 - 二氧化硅结构相似的导光特性。硅微结构光纤所测得的大模场面积和低光学损耗表明了其与现有光纤基础设施集成的潜力。
