Stable optical short pulse sources at 1.5 μm are becoming increasingly important in terms of realizing future ultrahigh speed optical communication. We report several new types of erbium-doped fiber laser that we have developed, which are capable of generating picosecond - femtosecond optical pulses. For low repetition rate short pulse generation, a passively mode-locked fiber laser with nonlinear polarization rotation can produce pulses of approximately 100 fs. With regard to high repetition rate pulse generation at 10-20 GHz, a harmonically and regeneratively mode-locked fiber laser can produce picosecond pulses. We also show that femtosecond pulse generation can be achieved at 10-20 GHz by compressing the output pulses of the regeneratively mode-locked fiber laser with a dispersion-decreasing erbium-doped fiber amplifier.
