An optoelectronic device includes a substrate and a first optoelectronic chip flush with a surface of the substrate. The device includes a cover that covers the substrate and the first optoelectronic chip. The cover comprises a cavity above a first optical transduction region of the first optoelectronic chip. The device also includes a second optoelectronic chip having a second optical transduction region spaced apart from the first optical transduction region and the cavity continues above the second optical transduction region.
