| 20100291489 | EXPOSURE METHODS FOR FORMING PATTERNED LAYERS AND APPARATUS FOR PERFORMING THE SAME - Methods include providing an article including a substrate, a first layer supported by the substrate, and an interface between the substrate and the first layer. The substrate is substantially transparent to radiation at a wavelength λ and the first layer is formed from a photoresist. The methods include exposing the first layer to radiation by directing radiation at λ through the substrate to impinge on the interface so that the radiation experiences total internal reflection at the interface. | 11-18-2010 |
| 20090152748 | Polarizer Films and Methods of Making the Same - In general, in one aspect, the invention features methods that include forming a roll of a first material into a substrate and forming a plurality of rows of a second material on the substrate, where the second material includes a metal, the rows of the second material extend along a first direction, the rows are spaced apart from one another, and adjacent rows are spaced apart by about 400 nm or less. | 06-18-2009 |
| 20090041971 | POLARIZER FILMS AND METHODS OF MAKING THE SAME - In general, in one aspect, the invention features an article that includes a layer including a plurality of spaced-apart portions of a first material extending along a first direction. The layer transmits about 20% or more of light of wavelength λ having a first polarization state incident on the layer along a path. The layer transmits about 2% or less of light of wavelength λ having a second polarization state incident on the layer along the path, the first and second polarization states being orthogonal. For wavelength λ, the first material has a refractive index of 1.8 or more and an extinction coefficient of 1.8 or more, and λ is 300 nm or less. | 02-12-2009 |
| 20080302982 | POLARIZER ELEMENTS AND SYSTEMS USING THE SAME - In general, in a first aspect, the invention features an article that includes a plurality of spaced apart ridges extending along a first direction, adjacent ridges being spaced with a period of Λ or less, each ridge comprising a plurality of layers where adjacent layers have different refractive indexes at a first wavelength λ | 12-11-2008 |
