Abstract

The development of innovative dielectric materials is crucial for advancing metasurface optics. Chalcogenides are well-known for their unique optical properties and broadband high transmission from visible to infrared, which promises to be an emerging material platform for metasurface optics. However, the lack of chalcogenide materials in visible transmissive metasurfaces remains. In this work, the designs and experimental works of the first chalcogenide visible transmissive metasurface optics based on the chalcogenide material Ge₂₃Sb₇S₇₀ (GSS) platform are presented. Taking advantage of its high refractive index and low optical loss in visible, chalcogenide metalens, focused meta-vortex, meta-holographic devices, and computational visible spectrometers are designed and fabricated with a commendable performance. This work establishes the groundwork for realizing diverse functionalities and broader integration of chalcogenide metasurfaces at visible wavelengths.

硫化物可见光透射超表面光学

新型介电材料的开发是推进超表面光学发展的关键。硫属化合物以其独特的光学特性和从可见光到红外的宽带高透射率而闻名，有望成为超表面光学的新兴材料平台。然而，在可见光透射超表面仍然缺乏硫系物质。本文介绍了基于硫系材料Ge23Sb7S70 （GSS）平台的首个硫系可见光超表面光学器件的设计和实验工作。利用其高折射率和低可见光损耗的特点，设计和制造了具有良好性能的硫系超构透镜、聚焦元涡、元全息器件和计算可见光谱仪。这项工作为实现硫族元表面在可见光波段的多样化功能和更广泛的集成奠定了基础。
