Abstract:
1. An integrated circuitry and optoelectronic packaged assembly, comprising: a transparent insulating substrate having first and second surfaces generally parallel to one another, at least one optoelectronic device bonded to said first surface of the transparent insulating substrate by flip-chip bonds of less than about 25 μm in height, such that said at least one optoelectronic device is optically accessible to optical signals through said substrate; electrical circuit structure at the first surface operatively coupled to the at least one optoelectronic device; at least one optical receiver or transmitter on the second surface of the transparent insulating substrate, wherein said optical receiver or transmitter comprises one or more alignment elements; mechanical alignment members on said second surface of the transparent insulating substrate, for engaging the alignment elements of said optical receiver or transmitter; and at least one alignment reference feature on the first surface of the transparent insulating substrate, wherein an optical path is formed between said optoelectronic device and said optical receiver or transmitter through said transparent insulating substrate, and wherein said optical path is free of any optical lens.
