Abstract:In order to achieve low refractive index detection in biomedical and material chemistry, a D-type microstructured optical fiber (MOF) sensor based on surface plasmon resonance (SPR) is proposed in this paper. The sensor uses gold nanofilm as sensing material between the core of the fiber and the plasma on the surface, and is coated at the open-ring. Parametric analysis of the open-ring diameter, air hole diameter and thickness of the gold nanofilm of the sensor was carried out by finite element method. The sim… Show more
