Abstract

Herein, a numerical study on standard slot waveguide and double hybrid plasmonic waveguide based on a silicon-on-insulator platform is presented. The geometric parameters of both the waveguides are optimized for the operational wavelength of 3.39 μm (absorption line of methane gas) to obtain the maximum evanescent field ratio (EFR). By utilizing Lambert-Beer’s law, the gas sensing capability of both the waveguides is determined. It is found out that both the waveguides of length 100 μm offer high EFR resulting in the 3dB decay of the propagating mode power for the methane gas concentration of 20-22 % in the chamber. The study provides the foundation for the practical realization of compact and highly sensitive gas sensors. Full Text: PDF ReferencesJ.Y. Yo, Y.S. Kwon, J.W. Lee, J.S. Park, B.H. Rho, W. II. Choi.

用于增强倏逝场吸收甲烷气体传感的标准槽波导和双混合等离子体波导结构

本文对标准槽波导和基于绝缘体上硅平台的双混合等离子体波导进行了数值研究。两种波导的几何参数均优化为3.39 μm(甲烷气体吸收线)波长，以获得最大的倏逝场比(EFR)。利用朗伯-比尔定律，确定了两种波导的气体传感能力。结果表明，当室内甲烷气体浓度为20 ~ 22%时，两种长度为100 μm的波导均具有较高的EFR，导致传输模式功率衰减3dB。该研究为实际实现紧凑、高灵敏度的气体传感器奠定了基础。全文:PDF姚，权永生，李家伟，朴家生，罗炳辉，吴伟。崔。"吸入甲烷引起的急性呼吸窘迫"，结核病和呼吸系统疾病74,120-123(2013)。交叉参考M.
