  • Patent number: 9052467
    Abstract: An optical fiber connector for transmitting high optical power, specifically power exceeding 1 kW. The connector includes an optical fiber having one of its ends in direct optical contact with a body made of a transparent material. The body in connection with the optical fiber end has a surface with an area exceeding the contact surface area of the optical fiber. The surface of the transparent body has a substantially conical design in order to provide an efficient flowing geometry around the contact end of the fiber, to increase the surface area for incident power loss radiation and deviate such radiation towards the optical axis of the connector.

  • Patent number: 8867876
    Abstract: An optical fiber splitter has a higher density fiber optic array that allows for smaller packaging. The optical fibers that extend from the optical fiber splitter have one end connectorized and their spacing at the other end reduced, thereby eliminating components that were heretofore required. A method of making the fiber optic array includes interleaving the optical fibers to reduce the overall dimensions of the fiber optic array and the fiber optic splitter. A tool is used to reduce the spacing of the optical fibers in the fiber optic array.

  • Patent number: 8840229
    Abstract: A continuous inkjet method includes modulating a liquid jet having a wavelength ?, and causing first and second droplets to break off from the liquid jet and travel along a path. The second droplet has a break off length that is longer than the break off length of the first droplet. The first and second break off lengths have a difference of at least one wavelength ? in response to stimulation pulses. A charge differential is produced between the first and second droplets. The trajectories of the first and second droplets are caused to diverge so that one of the first and second droplets is collected and the other of the first and second droplets is deposited on a surface. A transition in droplet creation is identified between stimulation cycles that produce the first and second droplets. A skip cycle is introduced between the stimulation cycles.

  • Patent number: 8724938
    Abstract: A tapered waveguide is provided for connection between an input waveguide and a photodiode. The width of the tapered waveguide increases as it extends from the input end that is connected to the input waveguide towards the output end that is connected to the photodiode. The tapered waveguide has an optimum half spread angle to cause higher-order mode excitation when receiving optical signal from the input waveguide. The photodiode either has a constant width or increases in width as it extends away from the output end of the tapered waveguide, its half spread angle being equal to or less than the half spread angle of the tapered waveguide.

  • Patent number: 8718415
    Abstract: Optical devices with versatile spectral attributes are provided that are implemented with one or more modulated and homogeneous layers to realize leaky-mode resonance operation and corresponding versatile spectral-band design. The first and/or higher multiple evanescent diffraction orders are applied to excite one or more leaky modes. The one- or two-dimensional periodic structure, fashioned by proper distribution of materials within each period, can have a resulting symmetric or asymmetric profile to permit a broadened variety of resonant leaky-mode devices to be realized. Thus, the attributes of the optical device permit, among other things, adjacent, distinct resonance frequencies or wavelengths to be produced, convenient shaping of the reflection and transmission spectra for such optical device to be accomplished, and the wavelength resonance locations to be precisely controlled so as to affect the extent to which the leaky modes interact with each other.

  • Patent number: 8606053
    Abstract: In an optical modulator, respective lights for where one input light has been branched, are input via a curved waveguide to a plurality of optical modulation sections arranged in parallel on the same substrate. In a Mach-Zehnder type optical waveguide, a spacing between the pair of branching waveguides of the adjacent optical modulation sections, is formed so as to become wider in the vicinity of a border of an input side polarization inversion region than in the vicinity of a start point of an interaction portion. As a result, even if a signal electrode of the optical modulation sections shifts at the boundary portion of the polarization inversion region, the spacing between the signal electrodes does not become narrow, and hence the radius of curvature of curved waveguides for guiding the input light to the respective optical modulation sections can be increased, so that it becomes possible to apply input light to the optical modulation sections at low loss.
