Abstract
A highly sensitive non-complex cored photonic crystal fiber sensor for hazardous chemical
sensing with water, ethanol, and benzene analytes has been proposed and is numerically analyzed
using a full-vector finite element method. The proposed fiber consists of a hexagonal core hole and
two cladding air hole rings, operating in the lower operating wavelength of 0.8 to 2.6 μm. It has been
shown that the structure has high relative sensitivity of 94.47% for water, 96.32% for ethanol and
99.63% for benzene, and low confinement losses of 7.31 × 10−9 dB/m for water, 3.70 × 10−10 dB/m
ethanol and 1.76 × 10−13 dB/m benzene. It also displays a high power fraction and almost flattened
chromatic dispersion. The results demonstrate the applicability of the proposed fiber design for
chemical sensing applications.
