LIGHT AMPLIFICATION OPTICAL FIBER AND LIGHT AMPLIFIER USING THE SAME |
| 摘要 |
A light amplifying optical fiber capable of restricting a reduction in amplifying efficiency and non-linearity caused by the concentration quenchin g of erbium ions. At least one of rare earth elements, having an ion radius at least 70% and up to 130% of that of erbium and excluding erbium, for example , Yb, is added to the core portion of an erbium-ion-added light amplifying optical fiber.
