Abstract: In this paper the dispersion properties of the elliptical core square-lattice PCF in a silica matrix have been studied. The dispersion curves for the fiber for different hole-to-hole spacing and air-hole diameter has been studies extensively. It has been shown that elliptical-core square lattice PCF with small hole to hole distance () and large-hole diameter (d) can be used for dispersion compensation. A comparison between Elliptical PCF with square and triangular PCF has been performed, taking into account the dispersion properties and the effective area. A final study on the two types of PCFs is carried out when they are single mode in the studied wavelength region.

Abstract: In this paper, the diallyl (oxybis(ethane-2,1-diyl)) dicarbonate (CR-39 monomer) of molecular structure that is a plastic polymer commonly used in the manufacture of eyeglass lenses, has been examined theoretically. The molecular structure of CR-39 monomer was optimized by Density Functional Theory (DFT) using B3LYP method with STO-3G basis set without specifying any symmetry for the title molecule. The non-linear optical properties were calculated at the same level and the title compound showed a good second order non-linear optical property. Besides, the frontier molecular orbital (HOMO and LUMO) energies and related molecular properties of CR – 39 monomer were investigated by theoretical calculation results.
