A method of fabricating a reflective notch coupler in an optical fiber has been developed. The coupler consists of a 45 ° microprism that penetrates into the core of a multimode optical fiber. One face, at 90 ° to the fiber axis, is nonreflective, and one face, at 45 ° to the fiber axis, is reflective. Our method of fabricating a notch and selectively mirroring only the 45 ° face is low-cost, precise, and easily scalable. The coupler allows near-100% coupling of light into an optical fiber from the side, while allowing coupling of any desired fraction of light out from the core at a 90 ° angle on the opposite side of the fiber.
