Latest Patents

Nagara's latest patents include an innovative optical waveguide and a method for preparing the same. This polymeric optical waveguide substrate features a first region with a polymer optical waveguide and an optical waveguide-free second region. The first and second regions are situated on the same substrate, with an adhesive layer positioned between the lowermost polymer layer of the optical waveguide in the first region and the substrate. A groove intrudes into the substrate at the boundary between these regions. The method for preparing the waveguide substrate involves applying an adhesive layer onto the first region while keeping the second region free of any adhesive layer. Following this, a polymer is applied to the entire surface of the substrate to form a polymer layer for the optical waveguide. The polymer layer is then cut at the boundary between the first and second regions, allowing for the removal of the polymer on the second region.
