Abstract

The field of metasurface optics is well-suited to leverage advanced materials due to their unique ability to tailor light–matter interactions at the sub-wavelength scale, providing a high degree of dynamic functionality. In this Letter, we explore the low-loss chalcogenide-based phase change material Sb2S3 and its integration into Mie-resonant metasurfaces to realize highly tunable near-infrared transmission-based filters. Through a combination of computational modeling, fabrication, and characterization of near-infrared Sb2S3 metasurfaces, we demonstrate spectrally selective filters with high optical densities that achieve an absolute optical transmitted contrast of over 80% via thermal stimulus. Our work highlights the potential for reversible non-volatile optical writing and color filtering, tunable both passively and actively.

用于可调谐近红外滤波的Sb2S3微波谐振介电超表面

超表面光学领域非常适合利用先进材料，因为它们具有在亚波长尺度上定制光-物质相互作用的独特能力，提供了高度的动态功能。在这篇论文中，我们探索了低损耗的硫化物基相变材料Sb2S3，并将其集成到mie谐振超表面中，以实现高度可调谐的近红外透射滤波器。通过计算建模、制造和表征近红外Sb2S3超表面，我们展示了具有高光密度的光谱选择性滤光片，通过热刺激实现了超过80%的绝对光透射对比度。我们的工作强调了可逆非易失性光学写入和彩色滤波的潜力，可被动和主动调谐。

期刊介绍： Applied Physics Letters (APL) features concise, up-to-date reports on significant new findings in applied physics. Emphasizing rapid dissemination of key data and new physical insights, APL offers prompt publication of new experimental and theoretical papers reporting applications of physics phenomena to all branches of science, engineering, and modern technology. In addition to regular articles, the journal also publishes invited Fast Track, Perspectives, and in-depth Editorials which report on cutting-edge areas in applied physics. APL Perspectives are forward-looking invited letters which highlight recent developments or discoveries. Emphasis is placed on very recent developments, potentially disruptive technologies, open questions and possible solutions. They also include a mini-roadmap detailing where the community should direct efforts in order for the phenomena to be viable for application and the challenges associated with meeting that performance threshold. Perspectives are characterized by personal viewpoints and opinions of recognized experts in the field. Fast Track articles are invited original research articles that report results that are particularly novel and important or provide a significant advancement in an emerging field. Because of the urgency and scientific importance of the work, the peer review process is accelerated. If, during the review process, it becomes apparent that the paper does not meet the Fast Track criterion, it is returned to a normal track.
