Abstract: An optical multi-chip module (MCM) is provided. A printed circuit board (PCB) overlies a package bottom and has die contact regions, each having at least one electrical interface. A first die contact region is formed in a PCB top surface recess, and an optical component die has a bottom surface with an area about matching the PCB top surface recess. The optical component die has an optical port with microlens. An electrical component die has a bottom surface with at least one electrical interface connected to the second die electrical interface, which is connected to the first die electrical interface via a PCB trace. A wire bond is connected between the electrical component die and a package interconnection lead. A cover assembly connector has an optical port with a microlens, configured to communicate with the optical component die optical port, and a fiber port to accept an optical fiber.

Abstract: An optical element assembly with integrally formed microlens is presented. A wafer is provided with a plurality of adjacent IC optical elements, each optical element having an optical transmission port in a wafer top surface. A microlens array is attached to the wafer top surface, so that each microlens in the array overlies a corresponding optical element optical transmission port. Then, a wafer of optical elements with attached microlenses is formed, where each microlens has a first lens surface adhering directly to a corresponding optical transmission port. Subsequent to forming the wafer of optical elements with attached microlenses, the wafer is diced forming a plurality of optical element assemblies. Each optical element assembly includes an optical element integrally formed with an attached microlens.

Abstract: Embodiments are directed to a duck head connector comprised of a connector for connecting to a power adapter and an electric plug that swivels about the face of the side of the plug, where flexible insulated wires connect the prongs of the electric plug with the contacts of the connector. The flexible insulated wires rotate together with the plug, with the length and shape of the wires enabling the wires to wrap around each other without becoming tangled. In an alternative embodiment, a pair of spring contacts connects the prongs of the electric plug with a pair of stationary half-ring contacts. The spring contacts swivel along the inner surface of the half-ring contacts when the plug rotates. Flexible insulated wires connect the stationary half-ring contacts to the contacts of the connector.
