  • Patent number: 8663754
    Abstract: A method of forming patterns on transparent substrates using a pulsed laser is disclosed. Various embodiments include an ultrashort pulsed laser, a substrate that is transparent to the laser wavelength, and a target plate. The laser beam is guided through the transparent substrate and focused on the target surface. The target material is ablated by the laser and is deposited on the opposite substrate surface. A pattern, for example a gray scale image, is formed by scanning the laser beam relative to the target. Variations of the laser beam scan speed and scan line density control the material deposition and change the optical properties of the deposited patterns, creating a visual effect of gray scale. In some embodiments patterns may be formed on a portion of a microelectronic device during a fabrication process. In some embodiments high repetition rate picoseconds and nanosecond sources are configured to produce the patterns.

  • Publication number: 20100231847
    Abstract: A method of fabricating a switchable liquid crystal polarization grating includes creating a degenerate planar anchoring condition on a surface of a reflective substrate. An alignment layer may be formed on a transmissive substrate and may be patterned to create a periodic alignment condition therein. The transmissive substrate including the patterned alignment layer thereon may be assembled adjacent to the surface of the reflective substrate including the degenerate planar anchoring condition thereon to define a gap therebetween. A liquid crystal layer is formed on the surface of the reflective substrate including the degenerate planar alignment condition. The liquid crystal layer may be formed in the gap directly on the alignment layer such that molecules of the liquid crystal layer are aligned based on the periodic alignment condition in the alignment layer. Related fabrication methods and polarization gratings are also discussed.

  • Publication number: 20100034964
    Abstract: A simple and efficient method for transforming conformation of parts of chains in the amorphous phase in a conjugated polymer to extended conjugation length (termed as ? phase) is disclosed. The ? phase acts as a dopant and can be termed self-dopant. The generated self-dopant in the amorphous host allows an efficient energy transfer and charge trapping to occur and leads to more balanced charge fluxes and more efficient charge recombination. For example, a polyfluorene film was dipped into a mixed solvent/non-solvent, tetrahydrofuran/methanol in volume ratio of 1:1, to generate a ?-phase content up to 1.32%. A polymer light emitting diode with the dipped polyfluorene film as a light emitting layer therein provides a more pure and stable blue-emission (solely from the self-dopant) with CIE color coordinates x+y<0.3 and a performance of 3.85 cd A?1 (external quantum efficiency 3.33%) and 34326 cd m?2.
