Abstract

A comparative analysis of different parameters of a hexagonal photonic crystal fiber doped with some other liquid materials, whose refractive indices are lower than the refractive index of the actual core, has been proposed in this paper. Circular air holes are placed in four hexagonal shaped rings. Three holes from the innermost ring are filled not only with air, but also with water, ethanol, and ether to demonstrate the overall analysis of confinement loss, dispersion, and effective area. Finite Element Method is used in the software known as COMSOL Multiphysics for the calculation of effective refractive indices, while the calculation of confinement loss, dispersion and effective area, and the comparison graphs have been plotted in MATLAB. The photonic crystal fibers doped with some specific liquid can also be used for the calculation of sensitivity of that particular liquid or can be used as liquid sensors. It has been observed that the effective refractive indices and the confinement loss not only vary by changing the wavelength, but also by varying the structural parameters like pitch length and diameter of air holes. For this research work, the Perfectly Matched Layer was kept constant and the responses were calculated between diameter of holes, confinement loss, dispersion, effective area, and wavelengths.
