  • Patent number: 10459293
    Abstract: Liquid crystal photonic devices and microcavities filled with liquid crystal materials are becoming increasingly popular. These devices often present a challenge when it comes to creating a robust alignment layer in pre-assembled cells. Previous research on photo-definable alignment layers has shown that they have limited stability, particularly against subsequent light exposure. A method of infusing a dye into a microcavity to produce an effective photo-definable alignment layer is described, along with a method of utilizing a pre-polymer infused into the microcavity mixed with the liquid crystal to provide photostability. In this method, the polymer layer, formed under optical irradiation of liquid crystal cells, is effectively localized to a thin region near the substrate surface and thus provides a significant improvement in the photostability of the liquid crystal alignment.

  • Patent number: 8767282
    Abstract: A plasmonic polarizer and a method for fabricating the plasmonic polarizer are provided. The method deposits alternating layers of non-metallic film and metal, forming a stack. A hard mask is formed overlying the stack. The hard mask comprises structures having dimensions and periods between adjacent structures less than a first length, where the first length is equal to (a first wavelength of light/2). The stack is etched through openings in the hard mask to form pillar stacks of alternating non-metallic and metal layers having the dimensions of the hard mask structures. Then, the hard mask structures are removed. In one aspect, subsequent to removing the hard mask structures, the spaces between the pillar stacks are filled with a dielectric material.
