Paper Abstract

Strong linear birefringence and dichroism is observed in optical metamaterial consisting of array of subwavelength elliptical holes in a silver film. Spectroscopic polarimetic measurements reveal structure's ability to convert linear polarized light by making it highly elliptical (ellipticity up to 1) and rotating the polarization plane by angles up to 90°. Refractive index difference for two eigenstates of the structure extracted from experimental data varies from 0.4 to 1.8 in the visible. Linear birefringence and dichroism effects together result in metamaterial's ability of separating frequency modes by putting them into different polarization modes.
