【摘要】 A simple fiber tip sensor for refractive index(RI) measurement based on Fabry-Perot(FP) interference modulated by Fresnel reflection is proposed and demonstrated.The sensor head consists of an etchinginduced micro air gap near the tip of a single-mode fiber.The microgap and the fiber tip function as two reflectors to form a FP cavity.The external RI can be unambiguously measured by monitoring the fringe contrast of the interference pattern from the reflection spectrum.The experimental results show that the proposed sensor achieves temperature-independent RI measurement with good linear response.The proposed sensor achieves a high RI resolution of up to 3.4×10 5 and has advantages of low cost and easy fabrication.
