OPTICAL FIBER, OPTICAL FIBER MODULE AND RAMAN AMPLIFIER |
| 摘要 |
<p><P>PROBLEM TO BE SOLVED: To obtain sufficient Raman gain while suppressing a nonlinear phase shift. <P>SOLUTION: The amplifying fiber 2a shows≥4 (m/W) Raman gain efficiency (GR/Aeff) by the excitation at 1,450 nm wavelength and≤3 ratio of a nonlinear parameterγat 1,550 nm with respect to the Raman gain efficiency (GR/Aeff) by the excitation at 1,450 nm. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
