Abstract: Disclosed embodiments demonstrate batch processing methods for producing optical windows for micro-devices. The windows protect the active elements of the micro-device from contaminants, while allowing light to pass into and out of the hermetically sealed micro-device package. Windows may be batch produced, reducing the cost of production, by fusing multiple metal frames to a single sheet of glass. In order to allow windows to be welded atop packages, disclosed embodiments keep a lip of metal without any glass after the metal frames are fused to the sheet of glass. Several techniques may accomplish this goal, including grinding grooves in the glass to provide a gap that prevents fusion of the glass to the metal frames along the outside edges in order to form a lip. The disclosed batch processing techniques may allow for more efficient window production, taking advantage of the economy of scale.

Abstract: Optical mirror elements for high bandwidth free space optical communication are produced by an electroforming replication technique. Onto the precision surface of a mandrel that is a negative of the required optical surface a layer of metal is deposited forming an exact copy of the mandrel surface and is then separated to form the required optical element. During the production process the mandrel may be coated with a variety of materials that are then separated together with the electroformed optical element during the release step to form a monolithic structure that includes a reflective coating. The mandrel remains unchanged by the process and can then be re-used. The high cost of conventional polishing techniques is therefore limited to the production of the mandrel. The replication process results in the production of low cost optical elements suitable for high bandwidth free space optical data transmission.
