| 摘要 |
<p>PROBLEM TO BE SOLVED: To solve a drawback that the Raman gain is limited as a problem of conventional techniques and to improve the wavelength region with the maximum amplification and the wavelength region with a flat gain. SOLUTION: The concentration of germanium added to the core 11 exceeds 30 mol% and germanium or phosphorus is added to the clad 12.</p> |
