ABSTRACT:
A holographic 1.times.N single-mode fiber optics coupler for coupling a single-mode monochromatic fiber optics input to N single-mode fiber optics outputs. A hologram of the output fiber bundle or the equivalent is recorded and then a reconstructed image is generated by illuminaing the hologram by means of a single-mode input signal on a single-mode optical fiber. The holographically generated image of the original fiber optics bundle is then coupled to the original fiber bundle or a substantially equivalent output fiber optics bundle providing a high efficiency, compact, and low cost 1.times.N fiber optics coupler with self-alignment features.
