摘要

本文设计了一种基于2DPC微腔环形谐振器的传感器，用于检测尿中葡萄糖浓度，范围在0 gm/dl-15 gm/dl之间。该传感器由连接六边形微腔环形谐振器的输入和输出直波导组成。通过改变微腔中选定孔的半径，使Q因子增加，Q因子最大可达8894。该传感器的灵敏度为107 nm/RIU，检出限为2.4299 × 10-3 RIU。利用时域有限差分法对PhC进行了建模和设计。如果尿液的折射率随尿液中葡萄糖浓度的变化而变化，则观察到波长的变化。这个原理用于检测尿中的葡萄糖浓度。传感器尺寸约为13 μm × 9.9 μm。

High Q-factor 2D PCMicrocavity Ring Resonator Based Biosensor for Biomedical Applications

In this paper, a sensor based on 2DPC microcavity ring resonator is illustrated and designed to identify the glucose concentration in urine, over the range of 0 gm/dl-15 gm/dl. The proposed sensor is consisted of input and output straight waveguides connected to a hexagonal-shaped microcavity ring resonator. The radii of selected holes in the microcavity are altered in such a way that Q factor is increased and achieved a maximum Q factor of 8894. The obtained sensitivity and detection limit of the sensor are 107 nm/RIU and 2.4299 x 10-3 RIU respectively. FDTD method has been used for modeling and designing of PhC. The wavelength shift is observed if the refractive index of urine is varied by varying the glucose concentration in urine. This principle is used for the detection of glucose concentration in urine. The size of the proposed sensor is about 13 μm × 9.9 μm.
