Nonlinear Optical Rectification in Square Tangent Quantum Wells
摘要/Abstract
摘要：
研究了正切平方量子阱（QWs）在不同温度、流体静压作用下的非线性光整流. 在有效质量近似的框架下，通过求解薛定谔方程得到本征函数和能量本征值；通过利用密度矩阵理论和迭代方法，得到非线性光学整流（OR）的解析表达式.相关计算结果表明，流体静压、温度、限制势能和QWs的直径对OR系数有影响.研究所得结果可以为探讨正切平方量子阱的非线性光学整流提供理论依据.
Abstract：
The nonlinear optical rectification of square tangent quantum well (QWs) under different temperature and hydrostatic pressure is studied in detail. In the framework of effective mass approximation, the eigen functions and energy eigenvalues are obtained by solving the Schrodinger equation. By using density matrix theory and iterative methods, an analytical expression of the nonlinear optical rectifications (OR) can be obtained. The calculation results show that the OR coefficients are affected by hydrostatic pressure, temperature, confining potential energy and the diameter of quantum wells. It provides the necessary theoretical basis for studying the nonlinear optical rectifications of square tangent quantum wells.
