论文摘要
我们提出了一种新型的光学涡流，称为跨越（CP）启发的类似Hermite-Gaussian-Gaussian-Gaussian样光学涡流（HGOV）。从理论上讲，我们研究了CP如何与圆柱形镜头的相位分离。我们还研究了HGOV的传播特性，该特征具有遗传性高斯的强度分布，但仍然保留了轨道角动量。此外，我们得出了HGOV的菲涅尔衍射积分，并研究了无穷大的纯度。此外，我们还展示了HGOV自我测量的新功能。最后，我们表明我们可以更改奇异点的相对位置和HGOV的方向，从而促进了光学微观流动的应用。
We propose a new kind of optical vortex called the Hermite-Gaussian-like optical vortex (HGOV) inspired by the crossphase (CP). Theoretically, we investigate how the CP is decoupled from the phase of a cylindrical lens. We also investigate the propagation characteristics of an HGOV, which has a Hermitian-Gaussian-like intensity distribution but still retains the orbital angular momentum. Furthermore, we derive the Fresnel diffraction integral of an HGOV and study the purity at infinity. Besides, we show a novel function of the self-measurement of the HGOV. Finally, we show that we can change the relative positions of singularities and the direction of an HGOV precisely, which facilitates applications in optical micromanipulation.
