An efficient optical fiber-to-waveguide coupling technique is described, using a novel transcision cut, alignment ways, and D-shaped fibers. Fiber-to-waveguide coupling efficiencies as high as 96% have been achieved with multimode graded-index fibers and ridge polymer optical waveguides. Advantages of using this new coupling technique include ease of fiber-to-waveguide alignment interior to the substrate edge, passive coupling, and high coupling efficiency.
