一种新的由交叉相位产生的类厄米-高斯光涡旋
A new kind of Hermite-Gaussian-like optical vortex generated by cross-phase
摘要：
我们提出了一种新的光学涡旋称为厄米高斯光学涡旋（HGOV）的启发，交叉酶（CP）。从理论上讲，我们研究了CP是如何从柱面透镜的相位解耦的。我们还研究了HGOV的传播特性，它具有类似厄米-高斯的强度分布，但仍然保留轨道角动量。此外，我们推导了全息光栅的菲涅耳衍射积分，并研究了其在无穷远处的纯度。此外，我们还提出了一种新的HGOV自测量功能。最后，我们表明，我们可以改变奇点的相对位置和方向的HGOV精确，这有利于在光学微操作的应用。
英文摘要：
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.
