| 摘 要： | 现有报道的PCF-SPR折射率传感器的检测范围普遍较窄,不能实现低折射率的检测,且工作波段多数集中在可见光或通信波段,这限制了传感器的应用范围.鉴于此,提出了一种基于D型双芯PCF结构的SPR传感器,使用氧化铟锡作为等离子体材料沉积在D型PCF抛光表面,并对该传感器的理论模型进行了分析,包括金属参数对传感性能的影响,P...

| Abstract: | The detection range of the PCF-SPR refractive index sensor reported in the past is generally narrow,and the detection of low refractive index cannot be realized,and the wavelength is mostly concentrated in the visible waveband or communication waveband,which limits the application range of the sensor.In view of this,an SPR sensor based on D-shaped dual core PCF structure is proposed.Indium tin oxide is deposited on the polished surface of D-shaped PCF as plasma material,and the theoretical model of the sensor is analyzed,including the influence of metal parameters on sensing performance and the influence of PCF structure parameters on sensing performance.The results show that the sensor can achieve an ultra-wide detection range with a refractive index of 1.27~1.39.Its working wavelength is in the near-infrared region of 1300~2600 nm,the highest sensitivity can reach 35000 nm/RIU,the resolution is 2.85×10-6RIU.The ultra-high sensitivity and ultra-wide refractive index detection range of the sensor can be applied to the detection of plasma,white blood cellsWBC],HemoglobinHb],intestinal mucosa of huma,human liver,acetone and other biological tissues,as well as in the fields of medicine and chemistry. |
