Paper Abstract

The interaction of light with a sub-wavelength period grating can be approximated by a uniform medium with an effective refractive index. The effective index is a function of the grating structure, the indices of its composite materials and the polarization of light. In this paper we report on the design, fabrication and testing of CD, DVD polarization selective hologram gratings based upon this principle. We first describe the design, fabrication and testing of a one-layer structure. We then consider the design, fabrication and testing of a two-layer structure. We show, how the two-layer structure produces similar performance however has the lower aspect ratio. The two-layer structure is also shown to be less sensitive to off design wavelength and incident angle. Both gratings have been designed to function with the wavelengths of CD, and DVD.
