Optical amplifier having a constant gain profile |
摘要 |
An optical amplifier includes a rare-earth doped optical fiber or rare-earth doped optical waveguide serving as an amplification medium where rare-earth ions have been doped in its core and/or clad, an excitation mechanism for exciting the amplification medium, and a plurality of optical resonator that causes laser oscillation at a plurality of wavelengths of amplified spontaneous emission light produced in the amplification medium.
