We study the confined states of a molecule formed by two laterally coupled quantum dots. The static electric field and incident plane wave laser field are considered with different polarization. The respective Shrödinger equation is obtained in the framework of the high-frequency limit of Floquet theory. It is shown that the electric field has a qualitative impact on the spatial symmetry of electronic states. An in-depth study of electric and laser field combined effects show a strong correlation between them. Additionally, we show that the linear, nonlinear and total optical absorption coefficients and relative refractive index of the considered structure can be effectively tuned by changing electric field strength and intense laser field parameter. Our results indicate the possibility of controlling the optical response of double quantum dots molecule for future applications in nanostructure-based quantum information science.

我们研究由两个横向耦合的量子点形成的分子的约束状态。静电场和入射平面波激光场被认为具有不同的极化。在Floquet理论的高频极限范围内，获得了相应的Shrödinger方程。结果表明，电场对电子态的空间对称性有定性影响。对电场和激光场联合效应的深入研究表明它们之间有很强的相关性。此外，我们表明，通过改变电场强度和强激光场参数，可以有效地调整所考虑结构的线性，非线性和总光吸收系数以及相对折射率。
