摘　　要：传感器种类繁多,光纤传感器以其小型化、性能优良等特点从众多传感器中脱颖而出。基于此,本文以表面等离子体共振理论为支撑点,使用有限元方法进行计算,设计并研究一种D型双凹槽单通道光子晶体光纤高折射率传感器。研究结果表明,在最优结构参数下该传感器传感效果良好,在1.32~1.41的宽检测范围内,最大灵敏度达到16200 nm/RIU,最大品质因数可达255.92 RIU-1。由此可知,本文所设计的传感器符合现代化发展需求,有望在医疗检测、生物传感等多方面实现应用价值。There are many types of sensors,and optical fiber sensors stand out from many sensors due to their miniaturization and excellent performance.Therefore,a D-type double-groove single-channel photonic crystal fiber high refractive index sensor is designed and studied by using the finite element method to calculate the surface plasmon resonance theory as the support point.The results show that the sensor has a good sensing effect under the optimal structural parameters,with a maximum sensitivity of 16200 nm/RIU and a maximum figure of merit of 255.92/RIU in a wide detection range of 1.32-1.41.It can be seen that the sensor designed in this paper meets the needs of modern development and is expected to achieve application value in medical detection,bio-sensing and other aspects.
