| Outline of Final Research Achievements |
We investigated pump power coupling technology for side-pumping of double-cladding-type Er-doped multicore fiber amplifier. We clarified that coupling efficiency and coupling length can be improved by controlling high-order modes of the pump power. Furthermore, we studied the applications of the investigated multicore amplifiers in optical fiber communication systems including radio on fiber and multi-level coherent optical communication systems.
