Subpicosecond optical solitons in dispersion-shifted optical fibers have been successfully amplified with an Er3+-doped single-mode fiber amplifier. The Er3+-doped fiber amplifier was pumped by two InGaAsP Fabry–Perot-type high-power laser diodes, and gains of 2.8 dB at 1.535 μm and 3.8 dB at 1.552 μm were obtained for solitons with pulse widths of 0.7–0.9 psec and peak intensities as high as 40 W. The transmission characteristics of the amplified solitons through a long dispersion-shifted fiber are also reported.
