Polymeric waveguide film with embedded mirrors for flexible optical interconnection

A polymeric waveguide film with embedded mirrors is presented for flexible optical interconnection. The waveguide was fabricated by a ultra violet (UV)-imprint method using a metalic imprint master. The waveguide patterns of the master were directly formed on a metallic body using ultra precision machining (UPM) method, and 45deg-angled mirrors were simultaneously constructed at the waveguide pattern ends. We manufactured a flexible waveguide film with embedded mirrors and found that the input beam entering into the film surface was well coupled the opposite surface.
