摘要：We investigate generation of superluminal vector optical solitons in a five-level M-type atomic system within active-Raman-gain regime. By analyzing the linear and nonlinear optical properties of the system, we demonstrate that the dispersion effects of the probe fields can be well balanced by self-phase and cross-phase modulation of the Kerr nonlinearity and various types of optical vector solitons with superluminal group velocity can be formed in the system. Moreover, by choosing proper parameters Manakov temporal vector solitons can also be realized in this atomic system.
