  • Arrangement consisting of a photodiode and an optical fiber
    Patent number: 6524017
    Abstract: In the arrangement according to the invention, a photodiode (PD) mounted on a submount (SM) and contacted by contact wires (GW) has its photosensitive surface (PS) attached directly to one fiber end by means of an optically transparent adhesive (CG). The fiber (OF) is fastened on a circuit board (BD) to which the contact wires (GW) of the photodiode (PD) are connected. The adhesive joint (CG) between photodiode (PD) and fiber (OF) represents the only mechanical attachment of the photodiode (PD).

  • Arrangement consisting of a photodiode and an optical fiber
    Publication number: 20010041033
    Abstract: In optical data communications, optical fibers are used as light guides, and photodiodes as receivers. The coupling between fiber and photodiode is of great importance. Conventionally, mechanical parts are used to hold the fiber and the photodiode in an optimum position relative to each other. These parts must be formed with high precision, so that their mass production is complex and expensive.
