摘要： A broadband wire grid polarizer for the visible spectrum has a plurality of elongated elements supported on a substrate. A region having a lower refractive index than the refractive index of the substrate is disposed between the elements and the substrate to reduce the longest wavelength at which resonance occurs. The region may comprise a plurality of ribs extending from the substrate and supporting the elements. The ribs may be formed by etching slots into the substrate using the elements as a mask. The region may also comprise at least one layer of dielectric film. In addition the region may be comprise ribs extending from the surface, each having at least one layer of dielectric film disposed thereon.

摘要： An image projection system has a wire grid polarizing beam splitter which functions as both the polarizer and the analyzer in the system. A light source produces a source light beam directed at the beam splitter which reflects one polarization and transmits the other. A liquid crystal array is disposed in either the reflected or transmitted beam. The array modulates the polarization of the beam, encoding image information thereon, and directs the modulated beam back to the beam splitter. The beam splitter again reflects one polarization and transmits the other so that the encoded image is either reflected or transmitted to a screen. The wire grid polarizing beam splitter is capable of being oriented at various incident angles with respect to the source light beam and modulated beam, and accepts relatively divergent light.

摘要： An embedded wire grid polarizer for the visible spectrum includes an array of parallel, elongated, spaced-apart elements sandwiched between first and second layers. The elements form a plurality of gaps between the elements which provide a refractive index less than the refractive index of the first layer. Regions may be formed between the elements and the first and/or second layers which also provide a refractive index which is less than the refractive index of the layers. The regions may be formed by film layers or ribs/grooves formed in the layers.
