Abstract:
To detect chemicals, we proposed a photonic crystal fiber (PCF) with hexagonal cladding
and a hexahedron core (THz). Circular air holes (CAHs) in the vestibule provide the basis
of the suggested sensor. To develop and evaluate our suggested hexahedron PCF sensor, we
employed the finite element (FEM) technique and perfectly matched layers (PML), which
utilized the optical parameters numerically. Here, 92.65%, 95.25%, and 90.70% are relatively
sensitive, and confining losses are low. The value 5.40 × 10−
08, 6.70 × 10−
08 dB/m,
and 5.75 × 10−
08 dB/m for three chemicals such as Ethanol (n = 1.354), Benzene (n = 1.366)
and Water (n = 1.330) and effective material loss (EML) of 0.00694 cm−
1. The suggested
Hx-PCF sensor has been successfully tested at 1 THz. We are certain that the suggested
sensor’s optimal geometric structure can be manufactured and that it can contribute to realworld
applications in biomedicine and industry. In terahertz areas, our suggested PCF fiber
is also suited for a wide range of medical signals and applications (THz).
