Abstract
An optical power divider is disclosed for single mode optical fibers. The fibers to be coupled are inserted in converging bores in a lower refractive index glass block which is collapsed about the fibers and drawn down. In the drawn down region the fibers are reduced in cross-section so that an appreciable proportion of the optical energy will be guided by the fibers while propagating in the surrounding lower refractive index glass block.
