We report in this work the numerical study of the supercontinuum phenomenon raised from Airy pulses within a silicon-on-insulator waveguide including loss effects, third-harmonic generation (THG) and negative-frequency Kerr (NFK) terms. This study is conducted through a modeling based on the full unidirectional pulse propagation equation model which allows to assume the existence of the NFK term in the Kerr nonlinearity with a spectral filtering. The various effects of the linear loss, the free-carrier absorption/ free-carrier dispersion, the two-photon absorption, the THG, the NFK, the peak power, the pulse duration and the pulse shape are explored.
