  • Publication number: 20160363728
    Abstract: Integrated target waveguide devices and optical analytical systems comprising such devices are provided. The target devices include an optical coupler that is optically coupled to an integrated waveguide and that is configured to receive optical input from an optical source through free space, particularly through a low numerical aperture interface. The devices and systems are useful in the analysis of highly multiplexed optical reactions in large numbers at high densities, including biochemical reactions, such as nucleic acid sequencing reactions. The devices provide for the efficient and reliable coupling of optical excitation energy from an optical source to the optical reactions. Optical signals emitted from the reactions can thus be measured with high sensitivity and discrimination. The devices and systems are well suited for miniaturization and high throughput.

  • Publication number: 20160363733
    Abstract: A method and system connects multiple cores within one fiber, e.g., a multi-core fiber (MCF), to multiple fibers with single-cores. The single-core fibers can then be terminated by traditional envelopes, such as a single core LC envelope. A connector holds the single-core fibers into a pattern that matches a pattern of all, or a sub group, of the individual cores of the MCF. The single-core fibers may all be terminated to individual connectors to form a fanout or breakout cable. Alternatively, the single-core fibers may extend to another connector wherein the single-core fibers are regrouped into a pattern to mate with the cores of another MCF, hence forming a jumper. One or more of the single core fibers may be terminated along the length of the jumper to form a jumper with one or more tap accesses.

  • Publication number: 20160363735
    Abstract: Technologies are generally provided to establish imaging through an optical fiber to enhance optical coupling between an optoelectronic device and the optical fiber. Imaging may be established by determining transmission properties of the optical fiber based on an observed light pattern, and applying a phase mask to input light based on the transmission properties to produce a focused light at the output end of the optical fiber. The focused light may be employed to determine a position and orientation of the optoelectronic device relative to the optical fiber by scanning the focused light and collecting light reflected from the scanning of the optoelectronic device at a charge-coupled device (CCD) camera and generating an image of the optoelectronic device. The position and orientation of the target device may be adjusted employing precision alignment tools to enhance alignment of the target device with the optical fiber for optimal coupling.
