Abstract
We developed image-fiber branching lens systems, namely, image-fiber couplers using graded-index rod-lens based 4f imaging microoptics. 2 × 2, 4 × 4, and 8 × 8 image-fiber star couplers were constructed. Optical alignment can be achieved only by butt-joint on V-grooves. Output-image configuration (erect or inverted) are uniform at all the output ports.
