| 摘 要： | An ultrashort 10-GHz pulse generation scheme was successfully demonstrated using a bulk mate- rial InGaAsP electroabsorption modulator to generate the seed pulse. A self-phase modulation-based re- shaper was used after the adiabatic soliton compression in a comb-like dispersion profiled fiber. Experi- ments and simulations confirm that the reshaper effectively removes the pulse pedestal and improves the pulse extinction ratio. As a result, the 10-GHz pulse had no pedestal, a high extinction ratio, and a pulse width of only 1.4 ps.
