ABSTRACT:
A unidirectional and bidirectional optical fiber couplers using polymer optical fibers having mirrors formed within the polymer optical fibers for reflecting optical signals. The mirrors comprise a notch having at least one surface angled with respect to the central axis of the optical fiber for reflecting the optical signal perpendicular to its central axis. A unidirectional embodiment allows input optical signals to be coupled from any combination of input optical fibers and transmitted into any combination of output optical fibers. A bidirectional embodiment allows optical signals from tapping fibers to be reflected in opposite directions along a first, or BUS optical fiber. Another aspect of the present invention is an apparatus and method for controlling the depth of the notch by monitoring residue power through the optical fibers while the notch is being cut.
