Abstract

A photonic crystal fibre (PCF)-based sensor has been proposed and thoroughly investigated for the identification of blood components, including red blood cells, haemoglobin, white blood cells, plasma, and water. To evaluate the sensor's sensing and propagation properties, a numerical analysis was performed using the COMSOL Multiphysics software. The proposed sensor design features an octagonal core and two layers of cladding with octagonal and circular air holes. At the optimal wavelength of 7.0 μm, the extensive simulation results confirms that the proposed sensor achieves high relative sensitivity of 99.89%, 99.13%, 97.95%, 97.77%, and 96.68% for red blood cells, haemoglobin, white blood cells, plasma, and water, respectively. Furthermore, the design demonstrates favourable confinement loss, propagation constant, V-parameter, spot size, and beam divergence. Therefore, the proposed PCF-based sensor holds great promise not only for medical sensing applications but also for optical communications. Its advanced design and highly sensitive capabilities make it a valuable tool for a wide range of potential applications in the biomedical and telecommunications fields.

用于血液成分传感的光子晶体光纤

一种基于光子晶体光纤(PCF)的传感器已被提出并深入研究用于血液成分的识别，包括红细胞、血红蛋白、白细胞、血浆和水。为了评估传感器的感知和传播特性，使用COMSOL Multiphysics软件进行了数值分析。所提出的传感器设计具有八角形核心和两层包层，具有八角形和圆形气孔。在7.0 μm的最佳波长下，广泛的仿真结果证实，该传感器对红细胞、血红蛋白、白细胞、血浆和水的相对灵敏度分别达到99.89%、99.13%、97.95%、97.77%和96.68%。此外，该设计还证明了良好的约束损耗、传播常数、v参数、光斑尺寸和光束散度。因此，所提出的基于pcf的传感器不仅对医学传感应用而且对光通信具有很大的前景。其先进的设计和高灵敏度使其成为生物医学和电信领域广泛潜在应用的宝贵工具。

期刊介绍： Sensing and Bio-Sensing Research is an open access journal dedicated to the research, design, development, and application of bio-sensing and sensing technologies. The editors will accept research papers, reviews, field trials, and validation studies that are of significant relevance. These submissions should describe new concepts, enhance understanding of the field, or offer insights into the practical application, manufacturing, and commercialization of bio-sensing and sensing technologies. The journal covers a wide range of topics, including sensing principles and mechanisms, new materials development for transducers and recognition components, fabrication technology, and various types of sensors such as optical, electrochemical, mass-sensitive, gas, biosensors, and more. It also includes environmental, process control, and biomedical applications, signal processing, chemometrics, optoelectronic, mechanical, thermal, and magnetic sensors, as well as interface electronics. Additionally, it covers sensor systems and applications, µTAS (Micro Total Analysis Systems), development of solid-state devices for transducing physical signals, and analytical devices incorporating biological materials.
