Abstract: The present disclosure describes optical and optoelectronic assemblies that, in some cases, include screen-printed micro-spacers, as well as methods for manufacturing such assemblies and modules. For example, an optoelectronic device mounted on a substrate can include an optical sub-assembly including a first optical element and a first micro-spacer on the optical element. The optical sub-assembly can be disposed over the optoelectronic device, with a first air or vacuum gap separating the first optical element from the optoelectronic device, and the first micro-spacer laterally surrounding the first air or vacuum gap.

Abstract: The present disclosure describes methods of attaching surfaces together. In one aspect, a method includes depositing a first adhesive onto a first surface of a first item, the first adhesive forming a pattern that at least partially surrounds a region of the first surface where there is no first adhesive. A second adhesive is jetted onto the region of the first surface, wherein the second adhesive has a viscosity lower than a viscosity of the first adhesive. The first surface of the first item and a second surface of a second item are brought into contact with one another. The method also includes curing the first and second adhesives. While the methods can be particularly suitable for manufacturing optical light guide elements, the methods also can be used in other contexts and applications as well.

Abstract: The present disclosure describes optical and optoelectronic assemblies that, in some cases, include screen-printed micro-spacers, as well as methods for manufacturing such assemblies and modules. For example, micro-spacers can be applied on a first optical element layer, and a second optical element layer can be provided on the first micro-spacers. By providing the second optical element layer on the first micro-spacers, the second optical element layer and the first optical element layer can be separated from one another by air or vacuum gaps each of which is laterally surrounded by a portion of the first micro-spacers.
