More Information
Summary:A coupling device for physically and optically coupling an input/output end of an optical fiber for routing optical signals, to and from optical receiver and/or transmitter. The coupling device includes a structured reflective surface that functions as an optical element that directs light to/from the input/output ends of the optical fiber by reflection, and an optical fiber retention groove structure that positively receives the optical fiber in a manner with the end of the optical fiber at a defined distance to and aligned with the structured reflective surface. The open structure of the structured reflective surface and fiber retention structure lends itself to mass production processes such as precision stamping. The coupling device can be attached to an optical transmitter and/or receiver, with the structured reflective surface aligned to the light source in the transmitter or to the detector in the receiver, and adapted in an active optical cable.
