Tunneling effect on second-harmonic generation in quantum dot molecule

摘要

The tunneling effect on second-harmonic generation (SHG) coefficient in quantum dot molecule (QDM) is investigated theoretically. By using the compact-density matrix approach and the iterative method, we obtain an analytical expression of the SHG coefficient and numerical calculations for GaAs QDM. The results show that the tunneling strength, Rabi frequency and the size of the QDM have influences on the SHG coefficient.
