本文提出一种贴膜D型光纤用于折射率传感,采用半解析方法建立模型,并分析计算在不同纤芯贴膜距离、贴膜厚度、贴膜折射率、工作波长条件下贴膜D型光纤工作性能,发现其折射率传感性能较普通D型光纤有较大提高,同时设计了两种工作在不同传感要求范围条件下的贴膜D型光纤.

In this paper,a D-shape fiber with slab waveguide film is proposed.This fiber can be used in refractive index sensing.Based on a semianalytical method,the sensing ability is analyzed under different conditions,such as varied distance between the core and surface,thickness of slab waveguide film,refractive of slab waveguide film and light wavelength.The result shows that refractive index sensing ability of the D-shape fiber with slab waveguide film is much better than the conventional D-shape fiber.Two D-shape fibers with slab waveguide film are designed for different sensing range.
