Abstract

We investigate the polarizing properties of periodic array of silver nanoellipsoids placed on top of a planar LED structure. The response of the particles is calculated with the periodic layered Green's tensor in the electrostatic limit with dynamic depolarization and radiation damping corrections. We investigate the degree of polarization and the total extracted power spectra depending on parameters like lattice period, axial ratio and particle size. The proposed model is applicable over a wide range of parameters and appropriate to optimize the given structure. The optimization procedure shows that particles in the size range of 100 nm are optimal to reach 50% degree of polarization and less than 15% absorbance for an uncollimated and unpolarized dipole source.
