Abstract

Holographic displays trade field of view against eyebox size because a spatial light modulator provides a fixed étendue. We pair a commercial 4-bit piston-mode phase light modulator (PLM) with a pixel-registered binary metasurface designed for an achromatic π phase step. Grouping the PLM into s×s superpixels while retaining native mask sampling increases the modeled angular-support area by s² with one passive element. Scalar simulations and three-color experimental captures at 450, 520, and 660 nm show matched operation from one fixed mirror bias. A fixed-depth diffractive element leaks 7.0% and 11.9% of the power into an unexpanded ghost at 450 and 660 nm, which the metasurface's full-wave-simulated zero order holds to 0.3% and 2.7%.

用二元π-超表面进行全息显示。

由于空间光调制器提供了一个固定的调制器，全息显示贸易视场与眼箱大小。我们将商业4位活塞模式相位光调制器（PLM）与设计用于消色差π相位步进的像素注册二进制超表面配对。在保留原生掩模采样的同时，将PLM分组为s×s超像素，使建模的角度支持面积增加了s2。标量模拟和在450,520和660 nm的三色实验捕获显示了从一个固定的反射镜偏差匹配的操作。固定深度的衍射元件将7.0%和11.9%的功率泄漏到450 nm和660 nm的未扩展幽灵中，而超表面的全波模拟零阶保持在0.3%和2.7%。

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.
