摘要

本文从理论上研究了各种变量对圆柱形 GaAs/Ga1-ηAlηAs 量子点的二次谐波发生（SHG）系数的影响。迭代法和紧凑密度矩阵法被用来确定 SHG 系数的表达式。结果表明，SHG 系数的变化与结构参数、外部条件和入射光子能量密切相关。

Nonlinear Optical Second Harmonic Generation Characteristics in Cylindrical GaAs/Ga1–ηAlηAs Quantum Dots

This article theoretically examines the effect of various variables on the second harmonic generation (SHG) coefficients of cylindrical GaAs/Ga1–ηAlηAs quantum dots. The iterative approach and the compact‐density matrix method have been utilized to determine the expression of the SHG coefficient. The outcomes demonstrate that the variation of the SHG coefficient is closely related to structural parameters, external conditions, and incident photon energy.
