ABSTRACT:
The present invention features a rectilinear optical coupler consisting of a single optical fiber terminating in an expanded, convex portion. An array of optical fibers consisting of a central optical fiber surrounded by six additional optical fibers has an end precision-ground to receive the convex, essentially spherical portion of the first optical fiber such that radiant energy in the single, input optical fiber is uniformly transferred to each of the fibers in the array. The convex/concave topology of the interface allows for uniform distribution of radiant energy in a small, rectilinear configuration which allows combining multiple couplers in an edge-to-edge arrangement.
