Abstract: Apparatus and methods for a nano-patterning process to fabricate nanostructures. A roller type mold is used to continuously imprint nanostructures onto a flexible web or a rigid substrate. The process includes a coating and an imprinting module, which rotate the web synchronously. Liquid resist materials are used for imprinting and the patterns are set by thermal or UV curing. The process is used to produce bilayer metal wire-grid polarizers, organic solar cells, and organic light emitting diodes.

Abstract: An optical element includes a first periodic structure portion being formed on a base portion and having a one-dimensional periodic structure in which a first medium and a second medium with a smaller refractive index than that of the first medium are alternately disposed in a first direction, and a second periodic structure portion being formed on the first periodic structure portion and having a periodic structure in which a third medium and a fourth medium with a smaller refractive index than that of the third medium are alternately disposed in the first direction. At an interface between the first and second periodic structure portions, a ratio of the first medium in the first periodic structure portion and a ratio of the third medium in the second periodic structure portion are different from each other. The element has a good form birefringence effect and a high reflection-suppressing effect.

Abstract: A stereo projection optical system includes a polarization converter, a 2-way wheel, a retarder, and an image engine. The polarization converter is configured for converting an incident light into a polarized light which have single polarization. The 2-way wheel includes a reflective region and a transmissive region. The reflective region is configured for reflecting the polarized light and the transmissive region is configured for transmitting the polarized light. The retarder is positioned to receive an emergent light from one of the reflective region and the transmissive region. The image engine is positioned to receive light output of the 2-way wheel and the retarder and configured for emitting the light output comprising spatial information. The stereo projection optical systems provide viewers three-dimensional images formed by two alternative polarized light beams whose polarizations are perpendicular to each other utilizing the 2-way wheel.

Abstract: A selectively absorptive, mulitlayer wire-grid polarizer for polarizing incident light includes a stack of thin film layers disposed over a substrate, including a wire-grid array of elongated metal elements having a period less than half the wavelength of the light. One of the layers can include a thin film layer with a refractive index greater than a refractive index of the substrate. One of the thin film layers can include a dielectric array of non-metal elements. One of the layers includes a material that is optically absorptive to the incident light.

Abstract: A complex polarizer system (“cross-polarizer”) including an arrangement of at least three polarizing beam splitting layers P1,P2,P3. P1 and P2 are arranged such that a beam transmitted by P1 is reflected by P2 without further polarization rotating components; P3 is arranged such that a beam reflected by P1 transmits P3 without further polarization rotating components. The congeneric processing of the two sub-beams of a beam split at P1 (both sub-beams go through a transmission and a reflection) eliminates the intrinsic asymmetries of simple polarizers with respect to purity and folding. Coupling of cross-polarizers results in efficient arrangements of systems which operate with complementarily polarized radiation, e.g. 2-channel image display systems with reflective spatial light modulators (e.g. Liquid Crystal on Silicon displays).
