  • Optical fiber coupler with overlapping core-extensions, and manufacturing methods of the same
    Patent number: 5287424
    Abstract: The basic embodiment of the present invention comprises an optical fiber having cores and a claddings, and core-extensions, wherein the individual core-extensions are built onto the core end facets in a shape of the diverging horn-like structure, with the sectional area increasing gradually as the individual core-extensions extend farther away from the core end facets to merge together and form a common core-extension for light mixing and coupling. The core-extension may be made of a photo-reactive material to be shaped after the diverging radiation pattern of light emitted from the core end facets.
