Optical Field Rotation of Finite Energy Airy-Hermite-Gaussian Beams in Medium with Potential Well
摘要
以带有抛物势的薛定谔方程为理论模型,采用分步傅里叶数值模拟方法,对势阱介质中的有限能量艾里-厄米-高斯光束的传输特性以及相互作用关系进行研究。结果表明,势阱介质会使有限能量艾里-厄米-高斯光束的光场结构在传输过程中发生旋转。随着势阱强度的增大,光束的光场结构完成旋转所需的传输距离越来越短。此外,进一步探讨了具有不同初始间隔的两个有限能量艾里-厄米-高斯光束在势阱介质中的相互作用关系,发现在传输过程中光束的光斑数量会发生变化。
Abstract
Herein, for the propagation and interaction of finite energy Airy-Hermite-Gaussian (FEAHG) beams in a medium with a potential well, a linear parabolic (Schr dinger-like) equation was applied as the theoretical model in a split-step Fourier numerical simulation. Results show that the optical field structure of FEAHG beams rotates in the medium with a potential well. The greater the intensity of the potential well is, the shorter the propagation distance for the optical field structure completing rotation is. In addition, further investigation of the interaction between two FEAHG beams with different initial intervals in the medium with a potential well reveals that the number of light spots during propagation changes.
