摘要：
In this article, a surface plasmon resonance (SPR) biosensor based on D-typed optical fiber coated by Al2O3/Ag/Al2O3 film is investigated numerically. Resonance in near infrared with an optimized architecture is achieved. Refractive index sensitivity of 6558nm/RIU (refractive index unit) and detection limit of 1.5x10(-6) RIU, corresponding to 0.4357nm/M and detection limit of 23nM in BSA (bovine serum albumin) concentration sensing, are obtained. The analysis of the performance of the sensor in gaseous sensing indicates that this proposed SPR sensor is much suitable for label-free biosensing in aqueous media.
