  • Patent number: 9971096
    Abstract: Embodiments herein include an optical system that passively aligns a fiber array connector (FAC) to a waveguide in a photonic chip. A substrate of the FAC is machined or etched to include multiple grooves along a common axis or plane to hold optical waveguides, or more specifically, the fibers of the optical cables in the FAC. To align the fibers to the photonic chip, one of the fibers is disposed in an alignment trench which has a width that is substantially the same as the diameter of the fiber. When the fiber registers with the alignment trench, the fiber is aligned with a waveguide disposed at the end of the trench. Because the pitch between the fibers can be precisely controlled, aligning one of the fibers using the alignment trench results in the other fibers becoming passively aligned to respective waveguides in the photonic chip.

  • Patent number: 8834036
    Abstract: An optical coupling structure of the present invention is configured with a lens body and a clamp. The lens body includes a lens section having the lens and a fixing section. The clamp includes a positioning section, a pressing spring, and a retaining section. The positioning section determines a position of the clamp except a position in a direction of the optical axis of the optical fiber. The pressing spring makes contact with a surface of the lens body having a normal direction matching with the end face of the optical fiber, and generates a returning force when the clamp moves in a direction opposite to the normal direction of the surface. The retaining section is formed in a portion of the clamp to press the optical fiber and retains the optical fiber not to move in a direction apart from the lens.

  • Patent number: 8811778
    Abstract: Systems and a method for routing optical signals are disclosed. One system includes a first large core hollow metal waveguide configured to guide a substantially coherent optical beam. A second large core hollow waveguide is optically coupled to the first waveguide with a coupling device. The coupling device is configured to divide the coherent optical beam into a transmitted beam and a reflected beam. Beam walk-off within the coupling device causes the transmitted beam to be shifted by an offset amount. The second large core hollow metal waveguide is shifted from the first large core hollow metal waveguide by approximately the offset amount to receive the shifted transmitted beam.

    Abstract: A method and apparatus for aligning optical transports in a ferrule. The transports are aliened in the ferrule by mounting the ferrule on a jig having grooves into which the ends of the optical transports are inserted for transversely aligning the fibers in the ferrule. A row of transports is placed in the ferrule cavity with the front ends of the transports extending past the ferrule and into the grooves of the jig, thereby laterally aligning the transports with the grooves. The fibers are affixed to the ferrule. The ferrule can then be removed from the jig and the front ends of the transports that extended into the grooves of the jig cleaved flush with the front face of the ferrule.
