Abstract
An optical coupler that provides for the direct mounting of integrated circuit(s). The coupler includes a two-part housing with grooves for accommodating optical fibers that are held in place when the two parts are put together. Circuitry is formed on the housing and solder balls, when heated to a liquid state and cooled (reflowed), are used to attach integrated circuit(s) onto the housing. At least one of these integrated circuit(s) is an optical die that is positioned in close proximity to the optical fibers to provide for the receipt and/or transmission of optical signals. The reflowing of the solder balls forms an electrical connection between the circuitry on the housing and the integrated circuit(s) and provides for alignment of these components. The housing is attached to a circuitized substrate using reflowed solder balls or wirebonds.
