  • Publication number: 20060193582
    Abstract: A composite polymer fiber comprises a polymer filler material and a plurality of polymer scattering fibers disposed within the filler material. At least one of the filler material and the scattering fibers is formed of a birefringent material. The refractive indices of the filler material and the scattering fibers can be substantially matched for light incident in a first polarization state on the composite polymer fiber and unmatched for light incident in an orthogonal polarization state. The scattering fibers may be arranged to form a photonic crystal within the composite fiber. The composite fibers may be extruded and may be formed into a yarn, a weave or the like. If the filler material is soluble, it may be washed out of the yarn or weave, and the scattering fibers may then be infiltrated with a resin that is subsequently cured.

  • Publication number: 20060170808
    Abstract: An optical low pass filter or blur filter, and method of making the filters, using an article having a birefringent surface for refracting incoming light when used with an image sensor. The birefringent surface of the article, such as a film, is structured or tilted such that, when the blur filter is placed within an optical path between a lens and the image sensor, the birefringent surface causes refraction of a light signal in the optical path into multiple light signals each being incident upon different sub-pixels within the pixels in the image sensor to prevent or reduce artifacts, such as undesirable color moiré effects, in the resulting digital image.

  • Publication number: 20060091412
    Abstract: A solid state light source includes an LED die that generates light of two polarization states. A medium is provided at or near an emitting surface of the LED die that preferentially reflects one polarization state back into the LED die and preferentially transmits the other polarization state out of the LED die, thus providing a solid state light source whose light output is at least partially polarized. Recycling of light within the LED die together with polarization conversion mechanisms can enhance efficiency and brightness of the polarized output.
