摘要

光纤表面等离子体共振(FO-SPR)传感器通过观察反射光的吸收率来测量折射率(RI)的变化。光纤表面等离子体共振传感器建模对于了解引起这种 RI 变化的基本过程至关重要。尽管存在两种类型的光线,即偏斜光线和经向光线,但文献中已开发出一种只考虑经向光线的 FO-SPR 模型。这种经向模型已在一些使用直通式 FO-SPR 传感器的出版物中证明了其适用性。然而,这种简化的 FO-SPR 模型无法正确模拟背反射式 FO-SPR 传感器,在这种情况下,漫射光在同一光纤端传输和收集。这里的研究表明,包含倾斜光线的广义 FO-SPR 模型能更准确地模拟背向反射 FO-SPR 传感器获得的光谱。考虑到偏斜光线入射面的变化,利用三维偏振光线追踪计算建立了广义 FO-SPR 模型。通过蒙特卡洛三维光线跟踪模拟,获得了背反射式 FO-SPR 传感器所需的角光线分布。接着,评估了加入光学元件和偏差的效果,以及通过调整金的相对介电常数和厚度对模型进行优化的效果。广义模型模拟出的 FO-SPR 吸光度宽度小于实验中的 FO-SPR 吸光度宽度。造成这种吸光度差异的原因尚不清楚,需要进行更多的研究。尽管如此,与简化 FO-SPR 模型相比,将倾斜射线纳入广义 FO-SPR 模型使其能够应用于更多样化的 FO-SPR 传感器,成为开发 FO-SPR 传感器的预测和分析工具。

Generalized Fiber-Optic Surface-Plasmon-Resonance Modeling Through Ray-Tracing

Generalized Fiber-Optic Surface-Plasmon-Resonance Modeling Through Ray-Tracing

Fiber-optic surface plasmon resonance (FO-SPR) sensors look at the absorbance of reflected light to measure changes in refractive index (RI). FO-SPR sensor modeling is essential in understanding the underlying processes that induce such RI changes. Despite two types of rays, i.e., skew and meridional rays, an FO-SPR model has been developed in the literature that only considers meridional rays. This meridional model has proven its applicability in several publications using pass-through FO-SPR sensors. However, this simplified FO-SPR model fails to simulate back-reflecting FO-SPR sensors properly, where diffuse light is delivered and collected at the same optical fiber end. Here, it is shown that a generalized FO-SPR model that includes skew rays more accurately simulates the spectra obtained in back-reflecting FO-SPR sensors. With the changing incidence plane of a skew ray in mind, the generalized FO-SPR model was built with three-dimensional polarization ray-tracing calculus. The necessary angular ray distribution of the back-reflecting FO-SPR sensor was acquired by a Monte Carlo three-dimensional ray-tracing simulation. Next, the effect of including optical components and deviations and model optimization by adjusting the gold relative permittivity and thickness was evaluated. The generalized model simulated FO-SPR absorbances with smaller widths than the experimental FO-SPR absorbances. The cause of this difference in absorbance is unclear and demands more research. Nevertheless, the skew ray incorporation in the generalized FO-SPR model enabled its application to a greater diversity of FO-SPR sensors compared to the simplified FO-SPR model both as a predictive and an analytic tool in the development of FO-SPR sensors.

期刊介绍: Plasmonics is an international forum for the publication of peer-reviewed leading-edge original articles that both advance and report our knowledge base and practice of the interactions of free-metal electrons, Plasmons. Topics covered include notable advances in the theory, Physics, and applications of surface plasmons in metals, to the rapidly emerging areas of nanotechnology, biophotonics, sensing, biochemistry and medicine. Topics, including the theory, synthesis and optical properties of noble metal nanostructures, patterned surfaces or materials, continuous or grated surfaces, devices, or wires for their multifarious applications are particularly welcome. Typical applications might include but are not limited to, surface enhanced spectroscopic properties, such as Raman scattering or fluorescence, as well developments in techniques such as surface plasmon resonance and near-field scanning optical microscopy.
