Abstract
A structure and a method of manufacturing a reflective notch coupler for an optical fiber are disclosed. The coupler is formed in an optical fiber by a pair of angled surfaces extending from the cladding of the optical fiber and meeting in the fiber's core to form an indentation in the fiber. One surface is reflectively coated and couples light into and out of the core of the optical fiber.
