An optical assembly (10) includes a rigid mount (12) with a recess (26) proximate a first side thereof, a substrate (14), and an optical die (16) flip-chip bonded to the substrate (14). The substrate (14) is secured to the first side of the mount and includes a plurality of die bonding elements (40), a plurality of optical apertures (32), and a plurality of external bonding elements (42). A plurality of traces (44) interconnect the die bonding elements (40) and the external bonding elements (42). The optical die (16) includes a plurality of optical elements, each element including an optical signal interface (48), the die being bonded to the plurality of die bonding elements (40) such that the optical signal interface (48) of each element is in registry with an optical aperture (32) of the substrate (14) and the die (16) is at least partially enclosed by the recess (26).

1. Field
Embodiments of the present invention relate to optical-to-electrical and electrical-to-optical transducers and connectors. More particularly, embodiments of the invention involve an assembly for quickly and reliably coupling a mechanically transferrable (MT) connector to an electrical circuit.
2. Description Of Related Art
Preferred embodiments of the present invention are described in detail below with reference to the attached drawing figures, wherein:
FIG. 1 is a perspective view of an optical assembly constructed according to a first implementation of the present teachings;
FIG. 2 is a perspective view of the optical assembly of FIG. 1, illustrating an MT connector attached to the assembly;
An optical assembly incorporating principles of the present teachings is illustrated in FIGS. 1-3 and designated generally by the reference numeral 10. The optical assembly 10 generally comprises a mount 12, a substrate 14, and an optical die 16. The assembly 10 generally interconnects an optical mechanically transferable (MT) connector 18 to an electrical circuit, such as a printed circuit board (PCB).
The mount 12 protects and gives rigidity to the substrate 14, protects the die 16, and provides a means for mounting the optical assembly 10 to an external structure, such as an external printed circuit board. Therefore, the mount 12 is preferably substantially rigid and may be constructed of plastic, ceramic, metal, or similar materials.
A plurality of alignment pin holes 20 generally extend from a front of the mount 12 to a back of the mount 12 along a first axis and receive alignment pins 21. As explained below, the alignment pin holes 20 provide a means for aligning the mount 12, the substrate 14, and the MT connector 18. A plurality of mounting holes 22 generally extend from a top of the mount 12 to a bottom of the mount 12 along a second axis. The mounting holes 22 may receive pins, screws, bolts, or other fastening devices to secure the mount 12 to an external structure.
