Abstract

In this paper, 2 D hexagonal photonic nano crystal cavity is structured and simulated after infiltrating hemoglobin and urine samples for refractive index biosensing application. The proposed sensor accompanies hexagonal cluster of dielectric rods whose radius is 240 nm and at lattice constant of 800 nm respectively. The refractive index of bio-samples is taken for different concentrations and because of connection among light and analyte, a shift in the resonant wavelength is observed. Simulation results reports generously proportioned shifting of resonant wavelength and elevated sensitivities for biosensor. Photonic band gap is determined by PWE method and simulation results have been investigated using OptiFDTD.

摘要

在本文中，在渗透血红蛋白和尿液样本后，对二维六角形光子纳米晶体腔进行了结构和模拟，以用于折射率生物传感应用。拟议的传感器随附半径为240 nm且晶格常数分别为800 nm的六边形介电棒簇。取不同浓度的生物样品的折射率，并且由于光和分析物之间的连接，观察到了共振波长的变化。仿真结果报告了共振波长的大体成比例的偏移和生物传感器灵敏度的提高。通过PWE方法确定光子带隙，并使用OptiFDTD研究了仿真结果。
