ABSTRACT:
A coupler for interconnecting transmission lines in an optical communication system. In a preferred embodiment it comprises an elongated bi-conically shaped rod of transparent material which continues into two cylindrical mixing rods. The lines are split up into two groups coupled to respective ones of the two plane endfaces of the coupler. The dimensions of each tapered central portion are determined such that the radiation pattern in the common plane of the identical minor bases is substantially hemispherical no matter what the direction of propagation of the light modes along the axis from one end to the other, given the numerical aperture of the associated transmission lines.
