Abstract

Amplification characteristics of erbium-doped optical fiber amplifier have been investigated using femtosecond soliton pulses with various wavelengths. Soliton trapping is not observed for 210 fs input pulses at 1.535 μm but the soliton self-frequency shift occurs along with the pulse-width narrowing. When the input pulse width is 470 fs, the soliton pulse is amplified by the optical gain at 1.535 μm, where the gain bandwidth is broader than the bandwidth of the input pulse. Amplification characteristics at other nonresonant wavelengths are also investigated using a femtosecond soliton pulse.
