Sensitivity improvement of aluminum-based far-ultraviolet nearly guided-wave surface plasmon resonance sensor
文献摘要：
An aluminum(Al)based nearly guided-wave surface plasmon resonance(NGWSPR)sensor is investigated in the far-ultraviolet(FUV)region.By simultaneously optimizing the thickness of Al and dielectric films,the sensitivity of the optimized Al-based FUV-NGWSPR sensor increases from 183°/RIU to 309°/RIU,and its figure of merit rises from 26.47 RIU-1 to 32.59 RIU-1when the refractive index of dielectric increases from 2 to 5.Compared with a traditional FUV-SPR sensor without dielectric,the optimized FUV-NGWSPR sensor can realize simultaneous improvement of sensi-tivity and figure of merit.In addition,the FUV-NGWSPR sensor with realistic materials(diamond,Ta2O5,and GaN)is also investigated,and 137.84％,52.70％,and 41.89％sensitivity improvements are achieved respectively.This work proposes a method for performance improvement of FUV-SPR sensors by exciting nearly guided-wave,and could be helpful for the high-performance SPR sensor in the short-wavelength region.
