ABSTRACT:
A method disclosure for making an economical fiber coupler including providing a glass tube having first and second end portions and a midregion, and a longitudinal aperture extending through it. Two suitably prepared glass optical fibers, each having a core and cladding, are disposed within the longitudinal aperture, the fibers extending beyond each end of the tube. The fibers are glued to each end portion. The midregion of the tube is evacuated, heated, collapsed about the fibers, and drawn to reduce the diameter of the resulting composite.
