  • Patent number: 8672558
    Abstract: Optical signals are transmitted via fiber optic cables. The cable ends have connectors that connect to fiber-optic adapters. The interface between a connector and its adapter typically creates unwanted signal reflections. These unwanted signal reflections are mitigated by including an eight degree angle-offset of one face of an optical fiber within the adapter itself, the other face of the optical fiber having no angle offset, and the adapter being contained within a rigid housing. The angle offset of the fiber optic face in the adapter is mated with a complementary angle offset of the optical fiber in the cable connector. Embodiments of the present invention avoid cable management issues presented by previous adapters that included flexible cable between its input and output the previous adapters being designed primarily as jumpers and not suitable for use in tight, crowded spaces.

The fiber stub makes direct optical contact with the cable endfaces to enable efficient optical transmission between interconnected cables while providing a low loss, low back reflection adiabatic transition between the waveguide cores of the two cables.

  • Patent number: 8398314
    Abstract: Embodiments of the invention are directed to an optical USB (OUSB) to enhance the data rate of USB by adding super-high data rate (e.g. 10 Gbps) optical communication on top of its current specification so that backward compatibility is achievable. Mechanical tolerances may be achieved by using embedded lenses to expand a beam emerging from the connector prior to entering its mating connector and using an identical lens in the mating connector to collimate the beam back onto a fiber.

  • Patent number: 8320723
    Abstract: This document discusses, among other things, a connector for an optical imaging probe that includes one or more optical fibers communicating light along the catheter. The device may use multiple sections for simpler manufacturing and ease of assembly during a medical procedure. Light energy to and from a distal minimally-invasive portion of the probe is coupled by the connector to external diagnostic or analytical instrumentation through an external instrumentation lead. Certain examples provide a self-aligning two-section optical catheter with beveled ends, which is formed by separating an optical cable assembly. Techniques for improving light coupling include using a lens between instrumentation lead and probe portions. Techniques for improving the mechanical alignment of a multi-optical fiber catheter include using a stop or a guide.

    Abstract: The optical module includes an optical device mounting substrate 1 and an optical multiplexer/demultiplexer 2. One laser diode and at least one photodetector, which are positioned in the same plane, are mounted on the optical device mounting substrate 1. The optical multiplexer/demultiplexer is prepared by mounting a wavelength-selective filter and a mirror on the front and back surfaces of a transparent substrate. The optical device mounting substrate and the optical multiplexer/demultiplexer are mounted in a package 3 in such a manner that the optical device mounting surface and the filter surface are not parallel to each other. The optical module also includes a first lens, which is positioned near the laser diode or monolithically integrated with the laser diode, and a second lens, which converges light coming out of the optical multiplexer/demultiplexer toward an optical fiber.
