We describe a dual-core microstructured optical fiber designed for refractive index sensing of fluids. We show that by using the exponential dependence of intercore coupling on analyte refractive index, both large range and high sensitivity can be achieved in the one device. We also show that selective filling of the microstructure with analyte can increase the device sensitivity by approximately 1 order of magnitude.
我们描述了一种用于流体折射率传感的双芯微结构光纤。我们表明，通过利用纤芯间耦合对分析物折射率的指数依赖性，在一个器件中可以实现大测量范围和高灵敏度。我们还表明，用分析物选择性填充微结构可以使器件灵敏度提高约 1 个数量级。
