Abstract: A method and system for affixing multi-core fiber (MCF) within a ferrule includes a UV light source and a light guide. MCFs are placed into epoxy filled holders, e.g., channels or v-grooves, of a ferrule. A first MCF in a first holder is clocked to orient its cores to a desired position. The light source is activated, and the light from the light guide is launched into an outer layer of the first MCF, like the cladding layer or a dedicated light carrying layer. The light in the outer layer will stay in the outer layer until it reaches the portion of the first MCF in contact with the epoxy, even if the light is launched from the far end of the fiber remote from the holder. At the holder, the light will leak out due to the similarity in the index of refraction. The leaking light will at least partially cure the epoxy to affix the first MCF within the first holder. The process may then be repeated for the remaining MCFs, so that each MCF may be clocked and affixed selectively rather than collectively.

Abstract: Described herein is a cast-molding process for producing contact lenses in a relatively short curing time. The short curing time has been achieved by adding a chain transfer agent into a lens-forming composition.

Abstract: The present invention describes methods and apparatuses for creating superposition shape images by superposed base and revealing layers of lenslet gratings. The superposition shape images form a message recognizable by a human observer or by an image acquisition and computing device such as a smartphone. The superposition shape images may be created by different superposition techniques ranging from 1D moiré, 2D moiré and level-line moiré superposition techniques to lenticular image and phase shift superposition techniques. Moiré superposition techniques enable creating superposition shape images at different apparent depth levels. Applications comprise the protection of documents and valuable articles against counterfeits, the creation of eye-catching advertisements as well as the decoration of buildings and exhibitions.

Abstract: Provided is a method for manufacturing bent optical fibers with which bent optical fibers having a quality difference effectively reduced can be manufactured without a reduction of the manufacturing yield. In the present embodiment, an elastic bending process and a heating process are alternately repeated. In the elastic bending process, a movement restricting member rotatable around a revolving shaft is rotated while an optical fiber having its leading end portion held by the movement restricting member is fed toward the revolving shaft to form bent portions at a part of the optical fiber. In the heating process, the optical fiber is irradiated with a laser beam to relieve stress at the bent portions. Thus, multiple bent portions at which the stress is relieved are formed in the optical fiber along the longitudinal direction of the optical fiber.
