Abstract

An interposer comprising a substrate having at least a top surface and a bottom surface, the top and bottom surfaces being substantially parallel; at least one series of bottom cavities on the bottom surface; at least one expansion cavity contiguous with the at least one series of bottom cavities, the at least one expansion cavity being larger than each of the bottom cavities; a perimeter defined on the bottom surface around the bottom cavities; at least one alignment fiducial on the top surface for cooperating with a corresponding fiducial on the detachable optical interface to optically couple an optical conduit attached to the detachable optical interface with at least one optical device; and the at least one optical device mounted to the substrate on at least a portion of the perimeter, the optical device configured to emit a diverging light beam or receive a non-diverging light beam.
