Abstract : Document describes a holographic coupler for fiber optic systems having a holographic element utilized in conjunction with an optical source and an optical fiber in order to direct and couple the beam emanating from the optical source into the fiber. The holographic element, source and optical fiber have the same relative position with respect to each other as (1) a photosensitive medium, (2) a means for sizing and shaping a beam of temporally and spatially coherent radiation to the same geometry as the optical source before the beam impinges upon the the photosensitive medium, and (3) the focal point of a converging beam of temporally and spatially coherent radiation impinging upon the photosensitive medium during the making of the holographic element used with the coupler.
