摘要： An enhanced substrate for use in printed circuit boards (PCBs) includes low-Dk-core glass fibers having low dielectric constant (Dk) cores. In some embodiments, the low-Dk-core glass fibers are filled with a low Dk fluid, such as a gas (e.g., air, nitrogen and/or a noble gas) or a liquid. After via holes are drilled or otherwise formed in the substrate, silane is applied to the ends of hollow glass fibers exposed in the via holes to seal the low Dk fluid within the cores of the hollow glass fibers. In some embodiments, the low-Dk-core glass fibers are filled with a solid (e.g., a low Dk resin). For example, a hollow glass fiber may be provided, and then filled with a low Dk resin in a liquid state. The low Dk resin within the hollow glass fiber is then cured to a solid state.

A first lamination film is fabricated by forming a clad layer by forming a first curable resin layer for clad formation on a first base film and curing the first curable resin layer, and forming a core portion by forming a second curable resin layer for core formation having a higher refractive index than that of the clad layer after cured on the clad layer and selectively curing the second curable resin layer. A second lamination film is fabricated by forming a clad layer by forming a third curable resin layer for clad formation on a second base film and curing the third curable resin layer. In the optical waveguide manufacturing method, the first lamination film in which the core portion is formed and the second lamination film are bonded together with a fourth curable resin layer for clad formation interposed therebetween, and the curable resin layer interposed between the first lamination film and the second lamination film is cured to form a clad layer.

摘要： A random array of holes is created in an optical fiber by gas generated during fiber drawing. The gas forms bubbles which are drawn into long, microscopic holes. The gas is created by a gas generating material such as silicon nitride. Silicon nitride oxidizes to produce nitrogen oxides when heated. The gas generating material can alternatively be silicon carbide or other nitrides or carbides. The random holes can provide cladding for optical confinement when located around a fiber core. The random holes can also be present in the fiber core. The fibers can be made of silica. The present random hole fibers are particularly useful as pressure sensors since they experience a large wavelength dependant increase in optical loss when pressure or force is applied.
