    Abstract: An optical fiber ribbon holding member capable of readjusting a position of an optical fiber ribbon without requiring a heating operation is provided. A holding member main body that has a U-shaped cross section and a space to which a plurality of optical fiber ribbons can be accommodate in a laminated state, and a lid body an opening surface of which has a reverse U-shaped cross section are employed. A latch structure is formed on wall portions of a lid body and a holding member main body, and engages to each other when the lid body covers the holding member main body. Heating operation is not required, and the optical fiber ribbons are held by only a simple operation of covering the lid body, so that the operation of holding the optical fiber ribbons is easily performed and readjustment of the position of the optical fiber ribbons can be performed.

  • Patent number: 8002477
    Abstract: Optical devices, components and methods for mounting optical fibers and for side-coupling light to/from optical fibers using a modified silicon V-groove, or silicon V-groove array, wherein V-grooves, which are designed for precisely aligning/spacing optical fibers, are “recessed” below the surface of the silicon. Optical fibers can be recessed below the surface of the silicon substrate such that a precisely controlled portion of the cladding layer extending above the silicon surface can be removed (lapped). With the cladding layer removed, the separation between the fiber core(s) and optoelectronic device(s) can be reduced resulting in improved optical coupling when the optical fiber silicon array is connected to, e.g., a VCSEL array.

The abrasive medium may be placed into contact with an optical fiber to induce a flaw in the optical fiber. The optical fiber is broken about the induced flaw to create an end face for fiber optic termination preparations. In one embodiment, a method for cleaving an optical fiber without employing a blade is provided. The method includes providing an optical fiber. A flaw is created in a portion of the optical fiber using a bladeless cleaver comprised of a body and a cleaver structure attached to the body. The cleaver structure is configured to actuate to place an abrasive medium in contact with the portion of the optical fiber to create a flaw in the optical fiber. The method further includes breaking the optical fiber at the flaw to create an end face.

    Abstract: An optical fibre that use index-guidance formed with a low index cladding or a microstructured cladding using voids/holes or low index features (404) together with multiple high index resonant cladding features (1205, 1206). One to three resonant cross sectional extending structure act as a filter by resonantly coupling light out to part of the cladding (1202) or other structures (fx. a high index outer cladding ring) that acts as light sink(s) at one to three wavelength when using one to three materials or features with different size, shape, refractive index profile or normalized frequency parameter. The fibre can be asymmetrical. The fibre can be adapted for suppression of higher order modes (HOM) and/or guiding light in a narrow spectral wavelength range and act as a band pass filter.

  • Publication number: 20100303418
    Abstract: A three rod bundle confined inside a sleeve is constructed as a light guiding fiber mechanical splicing device which is stiff, strong and precise, with no moving parts. The design also applies to splicing fibers to pre-polished optical connectors through a built-in model of this innovative mechanical splicer. Applying the Soddy circles formula and using a bin approach assists in deriving the exact rod sizes needed and sleeve bore size to accommodate the three-rod bundle, so that this apparatus can be properly designed to guide any size of light guide fibers and studs with minimum clearance. Rods of varying diameters are sorted into bins and chosen based upon the aperture desired, thus eliminating the need for tight tolerance of the diameters of the three rods. This unique design allows for construction of a precision virtual hole of very long depth, which enables two optical fiber studs to butt against each other with a core to core misalignment of less than 1 um for single mode fiber optics cables.
