Abstract

Symmetry breaking has been shown to reveal interesting phenomena in physical systems. A notable example is the fundamental work of Otto Stern and Walther Gerlach [Stern and Zerlach, Z. Physik9, 349 (1922)10.1007/BF01326983] nearly 100 years ago demonstrating a spin angular momentum (SAM) deflection that differed from classical theory. Here we use non-separable states of SAM and orbital angular momentum (OAM), known as vector vortex modes, to demonstrate how a classical optics analogy can be used to reveal this non-separability, reminiscent of the work carried out by Stern and Gerlach. We show that by implementing a polarization insensitive device to measure the OAM, the SAM states can be deflected to spatially resolved positions.

光学轨道角动量与斯特恩-格拉赫实验的类比。

对称性破缺已被证明能揭示物理系统中的有趣现象。近 100 年前，奥托-斯特恩（Otto Stern）和瓦尔特-格拉赫（Walther Gerlach）[斯特恩和泽拉赫，Z. Physik9, 349 (1922)10.1007/BF01326983]的基础性工作证明了与经典理论不同的自旋角动量（SAM）偏转。在这里，我们利用自旋角动量（SAM）和轨道角动量（OAM）的不可分离态（即矢量涡旋模式），展示了如何利用经典光学类比来揭示这种不可分离性，这让人想起斯特恩和格拉赫所做的工作。我们的研究表明，通过采用偏振不敏感设备来测量 OAM，可以将 SAM 状态偏转到空间分辨位置。

期刊介绍： The Optical Society (OSA) publishes high-quality, peer-reviewed articles in its portfolio of journals, which serve the full breadth of the optics and photonics community. Optics Letters offers rapid dissemination of new results in all areas of optics with short, original, peer-reviewed communications. Optics Letters covers the latest research in optical science, including optical measurements, optical components and devices, atmospheric optics, biomedical optics, Fourier optics, integrated optics, optical processing, optoelectronics, lasers, nonlinear optics, optical storage and holography, optical coherence, polarization, quantum electronics, ultrafast optical phenomena, photonic crystals, and fiber optics. Criteria used in determining acceptability of contributions include newsworthiness to a substantial part of the optics community and the effect of rapid publication on the research of others. This journal, published twice each month, is where readers look for the latest discoveries in optics.
