Paper Abstract

Optical signal distributions through side-emitting ports along a polymer optical fiber are demonstrated using etched micro-mirrors. Low-cost serial and parallel mirror fabrication processes are described. Near uniform light distributions through as many as 200 such output ports along a single fiber of 0.75 mm diameter and 0.485 numerical aperture are obtainable. A 4 X 16 plastic array coupler for fiber-to-fiber interconnections was fabricated. The fabricated couplers have maximum coupling efficiencies of up to 84.7% and 91.4% using, respectively, the total internal reflection type and metal coating type micro-mirrors. The coupling uniformity for the two cases are 84% and 76%, respectively. The coupling efficiency and its relation to misalignments are studied.
