摘要：
We have theoretically studied the optical bistability behaviors under an external electric field and a coupling laser field in double quantum dot molecule system with pi-type four energy levels. It can be adjusted by the system parameters such as the electronic cooperation parameter, the tunneling strength, the coupling laser field, the probe and coupling laser detuning. These results may be useful in the experiment and provide new types of all-optical switching.
