1. A method for forming an optical coupling assembly, the method comprising:

  • providing light reflecting or transmitting members having faces to be joined to one another, wherein the members comprise plates having a reflective coating;

    increasing bond surface energy of at least one of faces by at least one technique from the group consisting of plasma treatment, ion beam sputtering processes, reactive ion etching, striking of plasma onto the faces, ion implantation, and ion bombardment;

    joining the faces to fusion bond the faces to one another;

    cutting the fusion bonded plates into fusion bonded stacks of rods;

    applying a reflective coating to exterior faces of the stacks; and

    fusion bonding the faces of the stacks to one another.
