Patent ID: 7453058

Claim:
An apparatus comprising: a substrate having a first surface including at least one first optically active area; a device substantially supported by the substrate, the device having a second surface including at least one second optically active area positioned in a spaced-apart and opposed relationship with respect to the at least one first optically active area, the first surface separated from the second surface by a distance; at least one optical bump coupled to and in contact with the first surface and positioned between the first optically active area and the second optically active area, the at least one optical bump having a height less than the distance between the first surface and the second surface, the at least one optical bump having a surface facing the second optically active area that is substantially flat, and the at least one optical bump configured to couple light between the at least one second optically active area and the at least one first optically active area; and at least one solder bump that contacts both the first surface and the second surface.
