Abstract

A theoretical study on a novel planar waveguide surface Plasmon Biosensor is presented in this paper. The proposed biosensor has a configuration similar to the Otto excitation mechanism for surface Plasmon polaritons. The performance of the device with respect to key system parameters such as gap-width and device length is investigated using an eigenmode solver with perfectly matched layers (PML). Device resolution of 2.3 x 10(-6) RIU has been demonstrated for an aqueous analyte.

摘要

本文提出了一种新型平面波导表面等离子体生物传感器的理论研究。所提出的生物传感器具有与表面等离子体激元的奥托激发机制类似的结构。使用具有完全匹配层（PML）的本征模求解器研究了该器件在诸如间隙宽度和器件长度等关键系统参数方面的性能。对于水性分析物，已证明该器件的分辨率为2.3×10^(-6)RIU。
