| Outline of Final Research Achievements |
・Double cladding chalcogenide fiber with normal dispersion in the wide spectral region was deveoped. Broadband highly coherent supercontinuum covering the spectral range from 2 to 14 μm was genearated for the first time using the chalcogenide fiber. It was demonstrated that highly coherent light could be generated using chalcogenide fiber.
・A new microstructured optical fiber, which is called hybrid microstructured optical fiber, with glass rods around the core instead of air holes was designed. This fiber can have almost zero and flattened normal dispersion in the specctral range. Tellurite hybrid microstructured optical fiber with almost zero and flattened normal dispersion in the specctral range was successfully fabricated. Higly coherent and flattened supercontinuum was generated by 2 μm pumping using this tellurite hybrid microstructured optical fiber. This is the most flattened supercontinuum light ever generated.
