摘要

本文从理论上研究了子带间跃迁时具有克拉泽势的量子环的折射率变化。基于Nikiforov-Uvarov方法求解Schrödinger方程得到相应的波函数和能级,采用密度矩阵法和迭代法计算线性和非线性光学折射率变化。本文研究了围势深度、围势参数和量子环入射光强对量子环折射率变化的调制作用,并通过数值计算表明,不同参数的变化对量子环折射率变化有显著影响。

Linear and Nonlinear Optical Refractive Index Changes of Quantum Rings in the Kratzer Potential

In this paper, we theoretically investigate the refractive index changes of quantum rings with a Kratzer potential for inter-subband transition. The corresponding wave functions and energy levels were obtained by solving the Schrödinger equation based on the Nikiforov-Uvarov method, and the linear and nonlinear optical refractive index changes were calculated using the density matrix method and the iterative method. We have investigated the modulation of the refractive index changes by the depth of the confining potential, the parameters of the confining potential, and the incident light intensity of the quantum ring and have shown by numerical calculations that the change of different parameters has a significant effect on the refractive index changes of this quantum ring.
