A novel PCF-based sensor has been presented in this paper to sense different chemicals and biocomponents. The proposed biochemical sensor (BCS) comprises a simple arrangement of rectangular holes. The competence of this BCS in detecting analytes is evaluated employing the full-vector finite element method (FEM). Performance metrics prove the competence of this BCS in sensing various analytes that have a refractive index in the range of 1.33–1.48. The proposed BCS shows ultralower values for both the bulk absorption and confinement loss. This BCS attains a maximum of about 95.82% relative sensitivity at 2.5 THz. Also, the dispersion for this sensor is only 0.12 ± 0.011 ps/THz/cm at the same point of interest. These results prove that the proposed BCS will play a key role in sensing toxic chemicals, illegal drugs, biocomponents, etc. Besides, the simple rectangle-based PCF structure ensures the feasibility of fabrication by practicing the existing fabrication strategies.

新型基于矩形PCF(R-PCF)的THz态生化传感器(BCS)的设计和数值分析

本文提出了一种新颖的基于PCF的传感器,可以感应不同的化学物质和生物成分。提出的生化传感器(BCS)包括矩形孔的简单排列。使用全矢量有限元方法(FEM)评估了该BCS在检测分析物中的能力。性能指标证明了该BCS在检测折射率介于1.33–1.48范围内的各种分析物方面的能力。提议的BCS的整体吸收和限制损耗均显示出极低的值。该BCS在2.5 THz时可获得最大约95.82%的相对灵敏度。同样,在相同的关注点,该传感器的色散仅为0.12±0.011 ps / THz / cm。这些结果证明,拟议的BCS将在检测有毒化学药品,非法药物,生物成分等方面发挥关键作用。
