Optical amplifier for collectively amplifying optical signals having a plurality of multiplexed wavelengths |
摘要 |
Disclosed is an optical amplifier for collectively amplifying optical signals having multiplexed wavelengths. The optical amplifier enables a gain control in a range as wide as 1 dBm or larger, and employs a fiber that is doped with a rare-earth metal, such as erbium. The erbium-doped fiber in cross section is formed of a plurality of glass materials that are doped with erbium, and excitation light wavelength bands relative to the erbium-doped fiber are provided in a number equivalent to the count of the glass materials.
