“…In addition to getting the typical values for all the performance metrics, one of the key objectives of this study is to present a highly fabrication-friendly BCS, which is ensured by the presence of only rectangular holes in the PCF structure. R-PCF ensures heterodyne detection, and several sensors based on R-PCF have been proposed [41][42][43][44][45]. Besides, asymmetrical PCF structures comprising rectangles have already been implemented [46,47].…”

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.
