基于SPR效应的深刻蚀微开口双芯对称D型PCF传感器
Dual-core symmetric D-type PCF sensor with deep etching micro-opening based on SPR effect
摘要
Abstract
In order to further improve the sensing performance of biosensors,a dual-core symmetric D-type photonic crystal fiber(PCF)sensor based on the surface plasmon resonance(SPR)effect is designed.The sensor is prepared by stacking,stretching and chemical vapor deposition(CVD)technology,and has two different diameter pores,and the two kinds of pores are symmet-rical.The principle of glucose concentration detection system based on the sensor is introduced.The effects of metal materials,stomatal parameters and polishing parameters on the performance of the sensor are simulated and analyzed.The simulation results show that when the refractive index detection range is 1.26～1.41,the maximum wavelength sensitivity,resolution and glucose concentration detection sensitivity of the sensor can reach 24 600 nm/RIU,4.06×10-6 RIU and 2.73 nm/(g·L-1)respectively.关键词
