Paper Abstract

Taking into account parameters such as input pulse duration, peak power and dimension and dispersion of the nanofiber etc., using a femtosecond laser as a pump source and a nanofiber as a nonlinear element, we numerically simulated the supercontinuum generation (SCG). The results show that tapering the common fiber to nanometer-scale fiber provides tight field confinement and diameter-dependent dispersion, and narrowing the input pulse width to femtosecond could observe SCG easier. 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 changing dispersion and then the generation of supercontinuum.
