光學超穎介面可以透過調控不同的光學響應來實現高品質的多通道顯示，在光學著色技術與高安全性光學加密方面展現出巨大的潛力。基於超穎介面的結構色刻印技術可以明顯的展示出高色彩飽和度、明暗對比呈現和偏振可調性。
本篇論文以能提供寬頻高反射率的膜厚漸變之分散式布拉格反射鏡作為基板，與電漿子超穎介面結合後便能於次波長範圍內調控光學特性，當單一奈米結構與膜厚漸變之分散式布拉格反射鏡發生交互作用後，便能產生多個高品質因子(Q值)共振。我們透過超穎奈米結構與分散式布拉格反射鏡基板之間的耦合，搭配設計優化後的不同尺寸與旋轉角的單元結構展示結構色刻印，可以藉由改變奈米圖案的幾何尺寸與結構旋轉角來調控色彩飽和度與亮度，使得成像圖案能呈現漸層色彩變化。此外，透過不同旋轉角的奈米圖案以特定的方式排列，在入射和反射偏振光達成特定組合時，即可解密真實的圖案資訊。

This paper presents a broadband high-reflectivity distributed Bragg reflector (DBR) with a varying film thickness as the substrate. When combined with a plasmonic metasurface, it can manipulate optical properties within the subwavelength range. The interaction between a single nanostructure and the DBR with varying film thickness results in multiple high-quality factor (Q-factor) resonances. We demonstrate structural color imprinting through the coupling between the metasurface nanostructure and the DBR substrate. By optimizing the design of unit structures with different sizes and rotation angles, both the color saturation and brightness can be flexibly controlled. This allows the imaging pattern to exhibit gradient color variations. Additionally, by arranging nanostructures with different rotation angles in a specific manner, the actual pattern information can be decrypted when the incident and reflected polarized light achieve a specific combination.
