    摘要： An optical data storage system includes a laser diode to produce at least one light beam. An inorganic, dielectric grid polarizing beam splitter is disposable in the light beam to transmit a polarized light beam, and includes a stack of film layers disposed over a substrate. Each film layer is formed of a material that is both inorganic and dielectric. Adjacent film layers have different refractive indices. At least one of the film layers is discontinuous to form a form birefringent layer with an array of parallel ribs with a pitch of less than 390 nm. A drive carries a disc medium disposed in the polarized light beam to reflect a modified light beam. The grid polarizer is disposable in the modified light beam to separate the modified light beam into a reflected beam and a transmitted beam. A photo-detector is disposable in the reflected or transmitted beam.

    摘要： A wire grid polarizing beam splitter has a generally parallel arrangement of thin, elongated elements which interact with electromagnetic waves of a source light beam to generally transmit or pass light of one polarization, and reflect light of the other polarization. The arrangement of elements has a throughput greater than approximately 50%, and an extinction greater than approximately 100. In addition, the arrangement of elements has a period less than approximately 0.21 &mgr;m, and a width to period ratio of between approximately 0.25 to 0.76. The elements have a thickness of between approximately 0.05 to 0.5 &mgr;m.

    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 beam splitter can be an embedded wire grid polarizer with 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 or second layers.

    摘要： An optical polarization beam combiner or separator device includes a first optical beam carrier for carrying a first polarized beam and a second optical beam carrier for carrying a second polarized beam whose polarization is orthogonal to the polarization of the first polarized beam. First and second collimating/focusing lenses are positioned between the first and second optical carriers. A third optical beam carrier for carrying a non-polarized beam positioned on the same side of the two collimating/focusing lenses as the first optical beam carrier. An inorganic, dielectric grid polarizer is disposed between the first and second collimating/focusing lenses, and includes a stack of film layers disposed over a substrate. Adjacent film layers have different refractive indices. At least one of the film layers is discontinuous to form a form birefringent layer with an array of parallel ribs with a pitch of less than 400 nm, and greater than 200 nm.
