  • Patent number: 8888965
    Abstract: The present application relates to a process for the manufacture of transparent, large band gap, high refractive index and high temperature stable, non-stoichiometric titanium nitride thin film (TiNx0.1<x?1.0) for optical and optoelectronic devices comprising the steps of preparing the said film by magnetron sputtering in a mixture of argon and nitrogen atmosphere, as a thin layer on a substrate selected from stainless steel, amorphous fused silica, magnesium oxide, lanthanum aluminate and sodium borosilicate glass, the deposition of the said layer of the substrate being carried out at temperature between ambient and 873 K, the deposition being controlled by varying the nitrogen pressure. The invention also provides films prepared by this process and substrates coated with such films.

  • Patent number: 8437588
    Abstract: Optical vector vortex beams may be generated from few-mode or multi-mode optical fiber by introducing linearly or circularly polarized light into the fiber. By adjusting at least one of the polarization of the light, the incident angle of the light coupled into the fiber, and the length of the fiber, one or more vector modes supported by the fiber may be selected. The resulting output from the fiber may be a vortex beam that can be collimated and used for precise manipulation of objects on order of a micrometer or a nanometer in diameter.
