由矩形金属棒阵列组成的等离激元超表面以其在红外光谱范围内的强光学响应而闻名。在这项研究中，我们探索了用于编码信息的等离子体超表面的偏振敏感性。偏振敏感光学响应很大程度上取决于金属棒的方向，从而允许将信息编码到超表面中。在这里，我们证明了可以通过使用无掩模双光子聚合技术来获得二维偏振编码超表面。这种制造等离激元超表面的新颖方法使得偏振敏感超表面的快速原型设计和适应能够用于多路图像的编码。
Plasmonic metasurfaces composed of arrays of rectangular metallic bars are well known for their strong optical response in the infrared spectral range. In this study, we explore the polarization sensitivity of plasmonic metasurfaces for encoding information. The polarization-sensitive optical response depends strongly on the orientation of the metallic bars allowing the encoding of information into the metasurface. Here we demonstrate that a 2-dimensional polarization encoded metasurface can be obtained by using mask-less two-photon polymerization techniques. This novel approach for the fabrication of plasmonic metasurfaces enables the rapid prototyping and adaptation of polarization sensitive metasurfaces for the encoding of multiplexed images.
