“…In addition, the lower containment losses for ethanol were 5.95×10 -08 dB per m, for benzene 6.67×10−08 dB per m, and for water 5.80×10 −08 . Not only this, our proposed structure of H-PCF also defines a higher relative susceptibility of 89% in industrial and bio-medical sector and lower containment losses for chemical sensing than those found previously in the articles [15][16][17][18][19][20][21].…”

“…The different manufacturing processes of PCF are presented today, including stacking, jacketing, collapsing, and stretching on a conventional drawing tower. In recent times, however, the sol-gel process for the manufacture of the PCF structure with optical sensors is most commonly used and is better suited for the manufacture of the PCF structure based on sensors [21,[30][31][32][33][34]. In addition, the selective filling technique is better suited for filling or loading chemical products into the core areas with any PCF fiber structure [35][36][37][38][39][40][41].…”

This research article demonstrates a good simulation result for identifying and detecting various industrial chemicals in a Terahertz (THz) waveguide with a new heptagonal, five layers of heptagonal photonic fiber elliptic form, heptagonal clading shape (H-PCF). COMSOL 4.2 software based on finite element (FEM) methods and perfectly matched layers check our composition (PML). The different chemicals are also differentiated and identified by each other in different parameters H-PCF fibers show a high relative sensitivity of ethanol of approximately 86.50 percent after numerical analysis, Benzene around 89.35%, and water around 85.15% at a frequency of around 0.7 THz. In our experiment, we obtained very low confinement losses at 1 terahertz (THz) such as 5.95×10−08 dB/m for Ethanol 6.67×10−08 dB/m for Benzene, and 5.80×10−08 dB/m for water. Regarding these results, we can strongly recommend that our proposed heptagonal photonic crystal fiber (H-PCF) will be more congenial in biomedical, bio-medicine, and industrial areas for the identification and detection of various types of chemicals with the help of a THz waveguide.

“…Also, this type of sensor offers a lot more advantageous features that includes higher relative sensitivity, lower material and confinement loss (CL), light weight, robustness, cheaper, etc. All these features have widened the potential application of PCF-based sensors in chemical and bio-sensing applications, which includes the study of RNA and DNA [16][17][18], detection of cancerous cells [19][20][21], classification and detection of alcohol [22][23][24][25][26], detection of formalin [27,28], and surface plasmon resonance-based biosensors [29][30][31].…”

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.
