Abstract :
Experimental results on gain characteristics of an Er/sup 3+/-doped multicomponent glass single-mode optical-fiber amplifier are reported. This amplifier shows a gain spectrum with twin gain peaks of 1.535 and 1.543 mu m, providing a broadened gain bandwidth. The apparent 6-dB gain bandwidth is 12 nm. Furthermore, the signal gain of 17 dB and 15-mW pump power is realized at a signal wavelength of 1.536 mu m, and a signal gain coefficient of 1.4 dB/mW is achieved.<>
