  • Patent number: 10732335
    Abstract: Provided are a polarizing plate having excellent optical characteristics, and a method for manufacturing the polarizing plate. The present invention is provided with: a translucent substrate through which light passes in a working band; a bundle structure layer constituted of a columnar sheaf comprising one or more material from among dielectrics, metals, and semiconductors, the bundle structure layer being formed on the translucent substrate; an absorption layer formed on the bundle structure layer; a dielectric layer formed on the absorption layer; and a reflection layer formed on the dielectric layer and arranged as a one-dimensional lattice at a pitch that is smaller than the wavelength of the light in the working band. Because the bundle structure layer increases light absorption and light scattering, the result is that reflectivity can be reduced and excellent optical characteristics obtained.

  • Patent number: 9989687
    Abstract: A wave plate capable of increasing a birefringence quantity and being made into a thin film, and a method of manufacturing the wave plate. The wave plate includes a substrate, whereon convex portions and concave portions are formed with a period less than or equal to the wavelength of light that is used therewith, columnar portions, wherein fine grains of a dielectric material are layered by oblique vapor deposition of a dielectric material from two directions, in a columnar shape on the convex portions in the vertical direction relative to the surface of the substrate, and interstices that are located on the concave portions and disposed between the columnar portions. Using birefringence from the fine grains of the dielectric material and birefringence from the concave/convex portions of the substrate allows increasing the birefringence quantity and making a thin film.
