Abstract: A method for making a DVD-18 disc using primarily just conventional CD-type injection molding and sputtering equipments. Three substrates are molded. Each of two of the substrates has just one metallic information layer, with the opposite side being flat. The third substrate has two metallic information layers on its opposite sides. The three substrates are arranged in a sandwich configuration, with the substrate having two information layers being in the middle. Each of the outer substrates has a semireflective (gold) information layer that faces inwardly of the sandwich. The middle substrate has two fully reflective (aluminum) information layers. A very thin layer of glue is placed between the semireflective information layer on each of the outer substrates and one of the fully reflective information layers on the middle substrate.

Abstract: An injection laser assembly mounted upon a crystal substrate [10] employing a back facet monitor is disclosed. A graded index lens [34] focuses light from the, typically, high in diversion and low intensity rays output from the back facet of the laser [30]. To allow repeatable and efficient coupling the graded index lens [34] is mounted within a groove defined in the crystal. Several configurations for mounting a photodiode sensor [P1,P2] are possible.
