| Abstract: | The supercontinuum generation has been obtained in short conventional dispersion-shifted fiber using the femtosecond pulses
from a passively mode-locked erbium-doped fiber laser. In the experiment, the supercontinuum spectrum of >300 nm has been
observed by injecting 70-fs pulses into a several-meter dispersion-shifted fiber. The simulation of the evolution in the fiber
shows that spectral broadening arises from soliton dynamics when pumping using femtosecond pulses in the anomalous group velocity
dispersion regime of the fiber. |
