Abstract

An optoelectronic module includes a cover substrate including a passive optical element, a base substrate including an optoelectronic device, and a spacer layer joining the cover substrate to the base substrate. The spacer layer includes multiple first spacer elements fixed to a surface of the cover substrate and multiple second spacer elements fixed to a surface of the base substrate, in which each first spacer element is joined to a corresponding second spacer element through an adhesive layer, and in which the cover substrate, base substrate, and spacer layer define an interior region of the module in which the optical element is aligned with the optoelectronic device.
