ABSTRACT:
An optical fiber coupler for coupling optical fibers to one another comprises a holographic optical element (HOE), having an optical axis enclosed in a housing. The housing includes fiber guides adapted to receive at least one pair of optical fibers and to dispose at least an end of each of the pair of fibers substantially parallel to each other, substantially perpendicular to one face of the HOE, equidistant from th eoptical axis of the HOE, and equidistant from the surface of the HOE. The optical fiber coupler is compact, commercially versatile, inexpensive to manufacture and easy to connect.
