A self-focussing coupler for optical fibers includes a transparent body having the configuration of a paraboloid of revolution. One or more optical fibers are connected to the body at or near the point of focus. A flat face is formed at a normal to the axis of symmetry. A coupler assembly is formed by bringing the faces of two couplers together. Different optical components (beam splitting plates, bandpass filters, etc.) may be placed in an interface gap and bypass fibers may be added to alter the functions of the coupler assembly. |
