摘要：
Using a pulse shaping technique, we demonstrate the modulation of two-photon luminescence (TPL) of quantum dots through phase and polarization of the excitation femtosecond (fs) laser. The dependance of TPL intensity on the pi phase step position, square phase modulation time, and polarization angle of the fs laser is revealed.
