Abstract
Means and method is disclosed for achieving a low profile optical coupling to a module comprising an optoelectronic device together with other circuitry. Maintaining the optoelectronic device parallel to the substrate on which it and the associated circuitry are mounted enables the use of standard, well known manufacturing assembly techniques while providing electrical connection to the electric ports of said optoelectronic device. Subsequent to the electrical interconnection operation, the optoelectronic device is moved, together with its connections, to a position substantially orthogonal with the mounting substrate. Optical fiber, light coupling is utilized. The low profile of the overall module package is achieved by introducing the optical fiber in a direction generally parallel with the substrate and perpendicular to the light active surface of the optic port of the optoelectronic device. The structure and method are applicable to both hybrid integrated circuit assembly technology as well as to conventional metallic lead frames for plastic encapsulation.
