Supercontinuum generation (SCG) using a femtosecond Ti:Sapphire laser as a pump source and a nanofiber as a nonlinear element is investigated by numerical modeling. Many parameters are taken into account involving input pulse duration, peak power and diameter of the nanofiber. The results show that the narrower the input pulse is, the easier the SCG could be observed. The relation between the spectrum broadening and the diameter of nanofiber is not a direct proportion. According to our simulation, the dimension of the nanofiber plays an important role in effecting the dispersion and then the generation of supercontinuum.
