  • Patent number: 10737450
    Abstract: An optical element is produced by introducing a first liquid and a second liquid into respective inlets of a mold. The inlets are connected to a channel that extends to an outlet of the mold, the channel being tapered towards the outlet. The first and second liquids have different refractive indices and partially diffuse into each other inside the channel to form a multi-layer structure. The multi-layer structure is extruded through the outlet, onto a substrate. Curing the first and second liquids forms a solid optical element having a spatially varying refractive index profile in at least one dimension.

  • Patent number: 10640654
    Abstract: A coating composition containing a radiation-curable component, a photoinitiator, and a UV absorber is described. The coating composition may be applied to an optical fiber and cured to form a coating. The UV absorber provides a protective function by inhibiting unintended curing of the coating that may occur upon exposure of the fiber to UV light during fiber processing. The spectral overlap of the photoinitiator and UV absorber is minimized to permit efficient photoinitiation of the curing reaction over one or more wavelengths. Photoinitiation may be excited by an LED source with a peak emission wavelength in the range from 360 nm-410 nm.
