| Abstract: | Ultrashort pulses with a repetitive frequency of 1.368 GHz, the full width at half maximum (FWHM) of less than 100 ps and a peak power of 3.0 mW are obtained under the direct modulation of a fiber ring semiconductor laser. The wavelength dependence of threshold current is studied experimentally, and the obtained experimental results coincide with the theoretical analyses well. At the same time, the ways to improve the repetitive frequency and to decrease the pulse width are also concluded. |
