Abstract: This disclosure describes optoelectronic modules that include an image sensor having at least two regions separated optically from one another by a wall. The wall can include a bridge portion that extends over the image sensor and further can include a cured adhesive portion, part of which is disposed between a lower surface of the bridge portion and an upper surface of the image sensor. Various techniques are described for fabricating the modules so as to help prevent the adhesive from contaminating sensitive regions of the image sensor. The wall can be substantially light-tight so as to prevent undesired optical cross-talk, for example, between a light emitter located to one side of the wall and a light sensitive region of the image sensor located to the other side of the wall.

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.

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.
