| 摘 要： | Considering that the coupling among the heavy-hole exciton,light-hole exciton and the cavity photon can form bipolaritons in a quantum semiconductor microcavity,we calculate the group velocities of the cavity polaritons at different incident angles using the coupling model of three harmonic oscillators.The result indicates that the group velocities of the low and middle branches of the cavity polaritons have extrema,but the group velocities of the high branch increase with the increasing incident angle.
