| dc.description.abstract | A simple hexagonal lattice photonic crystal fiber model with liquid-infiltrated core for
different liquids: water, ethanol and benzene, has been proposed. In the proposed structure, three
air hole rings are present in the cladding and three equal sized air holes are present in the core.
Numerical investigation of the proposed fiber has been performed using full vector finite element
method with anisotropic perfectly match layers, to show that the proposed simple structure exhibits
high relative sensitivity, high power fraction, relatively high birefringence, low chromatic dispersion,
low confinement loss, small effective area, and high nonlinear coefficient. All these properties have
been numerically investigated at a wider wavelength regime 0.6–1.8 μm within mostly the IR region.
Relative sensitivities of water, ethanol and benzene are obtained at 62.60%, 65.34% and 74.50%,
respectively, and the nonlinear coefficients are 69.4 W−1 km−1 for water, 73.8 W−1 km−1 for ethanol
and 95.4 W−1 km−1 for benzene, at 1.3 μm operating wavelength. The simple structure can be easily
fabricated for practical use, and assessment of its multiple waveguide properties has justified its
usage in real liquid detection. | en_US |
