A photonic crystal fiber (PCF) for sensing of sulfuric acid is designed and analyzed using Comsol Multiphysics. To analyze the sensor performance, 0%, 10%, 20%, 30%, 40% H2SO4 solution is placed into the fiber separately and then relative sensitivity, confinement loss, birefringence, effective area ...

A mono-rectangle based photonic crystal fiber (PCF) model is designed as a biosensor. This model has been simulated and numerically analyzed using the finite element method (FEM). The anticipated model shows higher efficiency in detecting blood components, namely, red blood cell (RBC), white blood c...

In terahertz frequency (THz), we have proposed a hollow core photonic crystal fiber (HC-PCF) to sense chemical. The proposed sensor consists of square shaped air holes in the cladding region with a dumbbell shaped core which has been used to fill with sample liquid. A wide range of frequency has bee...

A square cored PCF (SC-PCF) sensor is proposed in this paper for the purpose of detecting detrimental chemical analytes (DEHP, BPA, and BPS) that are generally found in different plastic products. This SC-PCF sensor is capable of operating in the 1–2 THz regimes. Within this operable range, we found...
