摘要:
A method for manufacturing an optical device including at least one silicone elastomer optical waveguide includes the steps of providing a substantially rigid mold with a patterned surface, providing a core layer of a curable silicone elastomer, patterning the core layer by means of the patterned surface of the substantially rigid mold, curing the patterned core layer, and removing the substantially rigid mold from the patterned core layer. The method advantageously allows the manufacture of an optical device including at least one optical waveguide in a single step and in a reproducible manner.

摘要:
A slide fastener is provided. Each of two adjacent stringers includes a fastener tape which has outer and inner longitudinal edge portions and an intermediate portion between the outer and inner longitudinal edge portions and carries respective coupling elements provided in the fastener tape. Each stringer is provided with a plurality of decorative beads. The decorative members are provided on an outside surface of the fastener tape and the coupling elements are provided on an inside surface of the fastener tape. The decorative members are affixed to the outside surface of the fastener tape in which the intermediate portion is formed.
