| 摘 要： | 利用量子力学中的密度矩阵算符理论和迭代方法，得到Morse势阱中的光流系数和电光效应的解析表达式，并以典型的GaAs/AlGaAs莫尔斯量子阱为例进行了数值计算，研究结果表明，较大的光整流系数和电光效应与系统的非对称性有关，系统的非对称性越大，光整流系数和电光效应越大。

| Abstract: | Analytical expressions of optical rectification and electro-optic effects in Morse quantum well are obtained by density matrix approach and iterative method. Numerical results are illustrated for a typical GaAs/AlGaAs Morse quantum well. It is found that the optical rectification coefficient and electro-optic effects increase with the enhancement of the asymmetry of Morse quantum well. |
