Abstract
The statistic properties of photon emissions from single semiconductor quantum dots with V-type level driven by pulses are investigated theoretically Based on quantum regression theorem and master equations, the dynamic equations of the second-order correlation function of the photon emissions are deduced. The calculated results reveal that the efficiency of single photon emissions from two orthogonal polarization eigenstates (|x〉 and |y〉) reaches the maximum when the input pulses area is about π, and the probability of the cross-polarized single photon emission from |x〉 and |y〉 decreases with increasing of pulse width.
