Abstract : In the patent application broadband optical coupling for transferring light energy into and out of an optical path is provided by an optical transmission line having first and second portions with a discontinuity there-between in an alignment defining the optical path. A body member of material of relatively lower index of refraction has the first and second portions of the optical transmission line imbedded therein for maintaining total internal reflection along the optical transmission line and also has a transparent portion for completing the optical path across the discontinuity. One or more light propagating members are angularly imbedded in the body member for transferring light energy relative to the optical path through the transparent portion of the body member so that light energy may be either coupled into or out of the principal optical path defined by the optical transmission line.
