Paper Abstract

A numerical analysis of TE mode of electric field propagation through the interface between a thin film of TiO2 and periodic metal slits of silver is presented. The lossy metallic slits are optically described by Drude model. A grid of regular slits generates sharp hotspots of electric field at the exit plane. Adding a 2D rectangular photonic crystal made of air cylinders in titanium dioxide will enhance the electric field at the exit from the metallic slits without any loses in propagation distance and peak width. An optimization of geometrical parameters of metallic slits and photonic crystals is made for the propagation of a visible incident radiation with the wavelength of 650nm.
