| Abstract: | We have demonstrated optical amplification in a bismuth-doped silica glass in second telecommunication windows (1300 nm). The amplification was obtained at five different wavelengths between 1260 and 1360 nm and the amplification bandwidth is greater than 75 nm. This new gain medium is expected to be useful for application in ultra-wide broadband optical communication. |
