Abstract

This work presents a new configuration to generate vector beams, with shaped intensity and polarization distributions, based on two liquid-crystal spatial light modulators (SLM). The first device is used in a scalar mode to shape an input linearly polarized beam with a phase-only computer-generated hologram. Then, the Fourier transform is optically formed onto the second SLM, which operates as a pixelated retarder to spatially modify the state of polarization. The proposed optical architecture allows shaping the amplitude profile, while easily generating the cylindrically polarized vector beam pattern. Experimental results demonstrate the versatility of the approach.

用纯相位调制-延迟器光学结构产生的形状矢量光束。

本文提出了一种基于两个液晶空间光调制器（SLM）产生具有形状强度和偏振分布的矢量光束的新配置。第一个装置在标量模式下使用计算机生成的纯相位全息图来塑造输入线偏振光束。然后，傅里叶变换在第二个SLM上光学形成，第二个SLM作为像素化缓速器在空间上修改偏振状态。所提出的光学结构允许形成振幅轮廓，同时很容易产生圆柱偏振矢量光束模式。实验结果证明了该方法的通用性。

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.
