We demonstrate an electromagnetically induced electron transparency (EIET) in electron transport through a coupled triple-quantum-dots system under two radiation fields. The direct evidence of EIET is that an electron can travel from the left dot to the right dot without any effect from the center dot. The EIET (position, height, and symmetry) can be tuned by several controllable parameters of the radiation fields, such as the Rabi frequencies and detuning frequencies. The result offers a resonant transport tuning technique using radiation fields.
