  • Publication number: 20150305166
    Abstract: A method of patterning an unpatterned transparent conductive film, the unpatterned transparent conductive film comprising: a transparent substrate, a first conductive layer disposed on a first surface of the transparent substrate, and a second conductive layer disposed on a second surface of the transparent substrate, the first and second surfaces being disposed on two opposing sides of the unpatterned transparent conductive film, the first conductive layer comprising a first set of metal nanostructures, and the second conductive layer comprising a second set of metal nanostructures, the method comprising irradiating the first conductive layer with at least one first laser to form a patterned transparent conductive film, where the irradiation of the first conductive layer patterns the first conductive layer with a first pattern without also patterning the second conductive layer with the first pattern, and also where the unpatterned transparent conductive film and the patterned transparent conductive film bot

  • Patent number: 6909827
    Abstract: Two sub-assemblies in a fiber optic device are fitted to mounting faces of a central section. The mounting faces are typically flat and mutually orthogonal, thus permitting the adjustment of the two sub-assemblies in decoupled degrees of freedom. This results in a simpler adjustment procedure for aligning the two sub-assemblies. Furthermore, the mounting of the sub-assemblies using the orthogonal mounting faces permits the use of relatively thin layers of adhesive that reduce misalignment problems arising from mismatched thermal expansion when the temperature changes.

  • Patent number: 6839485
    Abstract: A particular focusing arrangement in a dual fiber collimator improves the transmission efficiency and ease of alignment of the collimator. In particular, the collimator includes two optical fibers mounted in a dual-fiber ferrule. The fiber end-faces are co-planar with the angle-polished end-face of the ferrule and displaced along the optical axis of the ferrule. The collimator unit also includes a first focusing element centered along the optical axis of the ferrule and positioned such that its back front focal point is between the two end faces of the fibers. An advantage provided by this arrangement is that by changing the fiber polish angle and polish azimuth, relative to a line connecting the fiber centers, superior coupling from one fiber to the other can be achieved, even with different working distances and at various wavelengths.

  • Publication number: 20040161220
    Abstract: In an improved approach to mounting optical elements in a fiber optic device, the positioning and orientation of the element are more accurate and the temperature dependent variations of the position and orientation are reduced. The mount has a protruding tip contact region on a mounting surface. Adhesive is supplied between the optical element and the mounting surface, and the optical element is pressed into contact with the protruding contact tip region, substantially expelling the adhesive from between the optical element and the protruding contact tip region. The adhesive is cured at a temperature exceeding the predetermined temperature range. This permits the adhesive to pull the element on to the contact tip region throughout the operating temperature range. This also permits the optical element to contact the mounting surface so that the optical element's surface is oriented parallel to the mounting plane.

  • Patent number: 6594418
    Abstract: Two sub-assemblies in a fiber optic device are fitted to respective end faces of a central section, along a longitudinal axis. The end faces of the central section are non-parallel. Butting the sub-assemblies to respective ends of the central section permits relative adjustment of the two sub-assemblies in substantially decoupled degrees of freedom. This results in a simpler adjustment procedure for aligning the two sub-assemblies. Furthermore, the mounting of the sub-assemblies using angled faces permits the use of relatively thin layers of adhesive that reduce misalignment problems arising from mismatched thermal expansion when the temperature changes.
