  • Patent number: 11897213
    Abstract: Techniques for controlling the flow of replication material (e.g., epoxy) during the formation of replicated optical elements include providing a transparent substrate (220) onto which the optical elements are to be replicated. The substrate (220) includes a structured UV curable shield (202) adhering to its surface. The UV curable shield (202), in turn, has openings (203) that expose portions of the surface of the transparent substrate (220) for replication of the optical elements. During the replication process, excess replication material (124A) may flow onto the UV curable shield (202), which subsequently can be cured so as to facilitate the release and removal of the shield (202) along with the excess replication material (124A).

  • Patent number: 11840034
    Abstract: Methods are disclosed for fabricating molds for forming eyepieces having waveguides with integrated spacers. The molds are formed by etching deep holes (e.g., 5 ?m to 1000 ?m deep) into a substrate using a wet etch or dry etch. The etch masks for defining the holes may be formed with a thick metal layer and/or multiple layers of different metals. A resist layer may be disposed over the etch mask. The resist layer may be patterned to form a pattern of holes, the pattern may be transferred to the etch mask, and the etch mask may be used to transfer the pattern into the underlying substrate. The patterned substrate may be utilized as a mold onto which a flowable polymer may be introduced and allowed to harden. Hardened polymer in the holes may form integrated spacers. The hardened polymer may be removed from the mold to form a waveguide with integrated spacers.
