Effect of group velocity dispersion on femtosecond pulse evolution in quantum well waveguide structures
چکیده انگلیسی

The paper deals with the theoretical investigation of ultrafast-pulse evolution in a semiconductor quantum well (QW). Semiconductor Bloch equations are used to obtain the polarization induced in the medium due to incident Gaussian electromagnetic beam. The partial differential equation with finite group velocity dispersion (GVD) is then used to analyze the effect of induced polarization on the pulse. The role of GVD on femtosecond pulse evolution in GaAs/AlGaAs waveguide is studied, giving due consideration to the intensity dependent group velocity of the medium.
