    Abstract: An optical system assembly technique utilizes a templating system for locating optical components 200 on optical benches 150. Specifically, the template system comprises a template substrate 102 that is placed over the optical bench. The substrate 102 has at least one alignment slot 104 that is formed through the substrate. This alignment slot 104 has an alignment feature 120, against which an optical component 200 is registered. In order to improve the accuracy of the alignment of the optical component on the optical bench, the slot 104 has a reentrant, such as a smooth or step, sidewall 106 extending from the alignment feature 120 into the template substrate 102. This way, there is a single point or near single point of contact between the optical component 200 and the template 102, to thereby improve the placement precision for the optical component on the optical bench 150.

    Abstract: A process for patterning dielectric layers of the type typically found in optical coatings in the context of MEMS manufacturing is disclosed. A dielectric coating is deposited over a device layer, which has or will be released, and patterned using a mask layer. In one example, the coating is etched using the mask layer as a protection layer. In another example, a lift-off process is shown. The primary advantage of photolithographic patterning of the dielectric layers in optical MEMS devices is that higher levels of consistency can be achieved in fabrication, such as size, location, and residual material stress. Competing techniques such as shadow masking yield lower quality features and are difficult to align. Further, the minimum feature size that can be obtained with shadow masks is limited to null100 nullm, depending on the coating system geometry, and they require hard contact with the surface of the wafer, which can lead to damage and/or particulate contamination.

    Abstract: An optical membrane device and method for making such a device are described. This membrane is notable in that it comprises an optically curved surface. In some embodiments, this curved optical surface is optically concave and coated, for example, with a highly reflecting (HR) coating to create a curved mirror. In other embodiments, the optical surface is optically convex and coated with, preferably, an antireflective (AR) coating to function as a refractive or diffractive lens.
