Abstract
We investigate the focused light from a metallic nanostructure by the coupling of a metallic nanoparticle and a metallic nanoslit flanked with periodic sinusoidal grating on one surface. We employ the boundary element method (BEM) to simulate the optical field distribution and the transmission resonant spectrum. The numerical results show that focused light are formed from the metallic nanoslit system. Such device can be used for miniature optical antennas in the optical regime, which can transmit or receive light along a specific direction for a given wavelength. Potential applications include that the coupling light in or out of fibers and the achieving the miniature optical source.
