Abstract
The invention contemplates an improved light-mode separator for orientation in axially offset adjacency to an end of an optical fiber, in a plane perpendicular to the fiber axis; separate concentric regions of the separator about the fiber axis have different light-converging properties such that the convergence point for each light-converging region is (a) offset with respect to the convergence point for each remaining light-converging region, and is also (b) independently externally accessible for focused-energy utilization without masking interference with any other converging light from the separator.
