  • Patent number: 10725373
    Abstract: A technique, and its applications, for high resolution, rapid, and simple nanopatterning. The general method has been demonstrated in several forms and applications. One is patterning nanophotonic structures at an optical fiber tip for refractive index sensing. Another is patterning nanoresonator structures on a sensor substrate for plasmonic effect related detection of VOCs. In the latter example, a graphene oxide coated plasmonic crystal as a gas sensor capable of identifying different gas species using an array of such structures. By coating the surface of multiple identical plasmonic crystals with different thicknesses of Graphene-Oxide (GO) layer, the effective refractive index of the GO layer on each plasmonic crystal is differently modulated when exposed to a specific gas. Identification of various gas species is accomplished using pattern recognition algorithm.

  • Patent number: 10365441
    Abstract: A two-dimensional (2D) optical fiber array component takes the form of a (relatively inexpensive) fiber guide block that is mated with a precision output element. The guide block and output element are both formed to include a 2D array of through-holes that exhibit a predetermined pitch. The holes formed in the guide block are relatively larger than those in precision output element. A loading tool is used to hold a 1×N array of fibers in a fixed position that exhibits the desired pitch. The loaded tool (holding the pre-aligned 1×N array of fibers) is then inserted through the aligned combination of the guide block and output element, and the fiber array is bonded to the guide block. The tool is then removed, re-loaded, and the process continued until all of the 1×N fiber arrays are in place. By virtue of using a precision tool to load the fibers, the guide block does not have to be formed to exhibit precise through-hole dimensions, allowing for a relatively inexpensive guide block to be used.

  • Patent number: 10309593
    Abstract: A lamp holder for a desk lamp and the desk lamp are disclosed. The lamp holder comprises: a light scattering plate, comprising a first face and a second face arranged oppositely to each other and side faces around ends of the first and second faces. The light scattering plate comprises at least one light-entering side face where light is capable of entering. Light can enter the light scattering plate from the light-entering side face of the light scattering plate, and after being scattered by the light scattering plate, a portion of the light exits from the first face of the light scattering plate and another portion of the light exits from the second face of the light scattering plate. The lamp holder provides not only sufficient lighting in the operational area located below the lamp holder, but also some lighting above the lamp holder.

  • Patent number: 10197743
    Abstract: A multi-fiber ferrule has lenses that have different prescriptions to disperse the light emitted from the multi-fiber ferrule. Alternatively, the lens for each individual optical fiber can be moved relative to the optical fiber or the optical fiber opening in the multi-fiber ferrule to cause the laser beam exiting the multi-fiber ferrule to be redirected into a structure that absorbs or blocks the laser.

  • Patent number: 10118381
    Abstract: A method for embossing a nanostructure, formed on a nanostructure punch, into a punch surface of a curable material which has been applied to a substrate. The method includes the following steps, especially following sequence: alignment of the nanostructure relative to the punch surface, embossing of the punch surface by a) prestressing of the nanostructure punch by deformation of the nanostructure punch and/or prestressing of the substrate by deformation of the substrate, b) making contact of a partial area of the punch surface with the nanostructure punch and c) automatic contacting of the remaining surface at least partially, especially predominantly, by the prestressing of the nanostructure punch and/or the prestressing of the substrate.

  • Patent number: 9989706
    Abstract: A multiport free-space wavelength division multiplexing (“WDM”) device is capable of handling multiple optical signals carried in multiple wavelengths (“?n”) using a prism. The WDM device includes an input collimator, prism, and optical filter. The input collimator receives an optical beam containing multiple wavelengths ?n traveling through free-space. The prism uses at least two (2) surfaces to generate a first optical beam which travels in opposite direction of the optical beam. The optical filter is situated at a predefined angle with respect to the interface surface of the prism for facilitating frequency separation as well as extracts a first wavelength (“?1”) from ?n to form a first light signal with ?1 and form a second optical beam with the remaining wavelengths of ?n. A collimator is used to guide the first light signal to a port.
