摘要

我们从理论上研究了典型的 GaAs/Al0.3Ga0.7As 量子点体系在静水压力和温度影响下的线性、三阶非线性和全光吸收系数变化。静水压力和温度对系统的影响是在有效质量的框架下处理的。在此方法中,利用密度矩阵法和迭代法得到了线性和非线性吸收系数的相对变化。此外,我们还揭示了静水压力和温度对非线性光学特性的影响机理,这对我们更好地理解其成因具有重要意义。我们证明了静水压力和温度会改变有效质量,从而导致系统的线性和非线性光学特性发生显著变化。此外,我们还揭示了有效质量对非线性光学特性的影响机理,这对我们更好地理解其成因具有重要意义。

Tunability of the nonlinear optical absorption in a GaAs/Ga0.7 Al0.3 As spherical quantum dots under external factors

We theoretically studied the linear, third-order nonlinear and total optical absorption coefficient changes of a typical GaAs/Al0.3Ga0.7As quantum dot system under the influence of hydrostatic pressure and temperature. The influence of hydrostatic pressure and temperature on the system is treated within the framework of effective mass. In this method, the relative changes of linear and nonlinear absorption coefficients are obtained by using density matrix method and iterative method. In addition, we also reveal the mechanism of the influence of hydrostatic pressure and temperature on the nonlinear optical properties, which is of great significance for us to better understand the causes. We have shown that hydrostatic pressure and temperature change the effective mass, resulting in significant changes in the linear and nonlinear optical properties of the system. In addition, we also reveal the mechanism of the influence of effective mass on the nonlinear optical properties, which is of great significance for us to better understand the causes.

期刊介绍: This journal establishes a dedicated channel for physicists, material scientists, chemists, engineers and computer scientists who are interested in photonics and nanostructures, and especially in research related to photonic crystals, photonic band gaps and metamaterials. The Journal sheds light on the latest developments in this growing field of science that will see the emergence of faster telecommunications and ultimately computers that use light instead of electrons to connect components.
