Microstructured optical bers (MOF) are a new generation of optical bers that have a huge exibility on choosing the location of the zero dispersion wavelength, ZD which can be chosen to be very close to the visible and even in the visible, allowing soliton propagation in the near infrared. Moreover, the nonlinearity of silica with femtosecond radiation produces a broadening of the spectra, which is called supercontinuum (SC), due to several nonlinear e ects, as self phase modulation (SPM), cross phase modulation (XPM), dispersive wave generation and stimulated Raman scattering. I focused my work on the study of visible dispersive waves generated when a special phase matching condition between initial input pulse and some wave in the normal dispersion regime is ful lled.
