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.

A modular building block for supporting arrays of microlenses, microlasers and microphotodetectors, etc. in an optical beam relay system used as an optical interconnection network. The building block includes a frame member on which is mounted the array. The frame member includes a base portion that is press fitted to the smooth top surface of a plate member. The bottom surface of the plate member includes a rail portion that is secured into a groove in the support structure, such as a table, that also supports various elements of the optical interconnection network.

A low-cost star-coupler assembly primarily for use in optical data networks is fabricated from three modular components. The first component is a support plate having at least two sets of grooves into which polymer optical fibers may be placed and a central aperture. The second component is a waveguide plate which is designed to fit in the aperture. The third component is a cover plate having alignment means for aligning the components in fixed relationship and for holding polymer optical fibers in the grooves securely in place. The coupling structure is most useful with large-core polymer optical fibers. The modular design facilitates replacement of fibers. The components may be fabricated by injection molding thereby reducing the cost.
