| Abstract(in English) | With the aim to produce a higher, wider, and flatter gain bandwidth of Er-doped fiber amplifier, a new structure is proposed and described with respect to the gain characteristics. The fiber structure consists of seven Er-Al co-doped cores covered with primary clad layers in a second clad outer layer. The aim of the amplifier is achieved by doping Al of a high concentration and nearly equal launching in at low laser level with a 0.98μm pump laser for each Er-doped core. By analyzing the optimum conditions for the fiber structure and fabricating, the amplifier with a gain of more than 40dB and a 1dB spectral bandwidth of about 15nm is obtained. For a gain of about 30dB, the 1dB spectral bandwidth can be broadened to more than 20nm with a wider spectral bandwidth compared with the conventional EDFA being obtained. The best value of the noise figure was 4.5dB. |
