“…This is better than the results of earlier studies in Refs. [8][9][10][11][12][13]. A smaller effective area results from the light confinement becoming more concentrated at increasing operating frequency, f. When the frequency is increased from 0.9 THz to 2 THz, Figure 9 shows the effective area of the photonic crystal fiber for the ideal core diameter.…”

“…Photonic Crystal Fiber (PCF) has provided novel possibilities for improving photonic instruments for sensing and communication applications. The design of this kind of glass fiber offers the implementation of a wider range of optical properties, including indefinite single-mode operation, a higher effective core area, increased transparency, design flexibility, and low loss [4][5][6][7][8][9][10][11][12].…”

This work proposes a hollow-core photonic crystal fiber-based edible oil sensor in the terahertz (THz) range (e.g., 1.0THz ≤ f ≤ 3.0THz) and different sensing characteristics are numerically analyzed. The suggested sensor’s performance was assessed by means of COMSOL Multiphysics, a commercial program that uses the finite element approach. The computational results indicate that the relative sensitivity is 85.591%, 84.648%, 82.625%, 82.683%, and 79.161%, respectively, at f = 2.2 THz, for several types of sunflower oil, mustard oil, coconut oil, olive oil and palm oil; and the corresponding effective areas are 7.22×10-8 um2, 7.09×10-8 um2, 6.83×10-8 um2,7.09×10-8 um2, 6.5231 ×10-8 um2. In addition, the effective material loss for sunflower oil, muster oil, coconut oil, olive oil, and palm oil has been found to be 0.02561 cm-1, 0.027054 cm-1, 0.030322 cm-1, 0.028854 cm-1 ,0.035427cm-1 respectively. Moreover, the proposed sensor also has low confinement loss are 1.55×10-8 dB/m, 1.63×10-8 dB/m, 1.31×10-8 dB/m, 1.99×10-8 dB/m, 4.0345×10-8 dB/m.This proposed sensor can be fabricated using extrusion and 3D-printing technologies, and due to its augmented detecting capabilities, it can be a vital part of oil sensing devices implemented in real life such as industry fields.
