“…Nanostructured arrays with periodic variation of optical constants have been studied extensively and developed in different aspects to achieve various optical characteristics, such as wavelength/polarization/angle filtering, − optical field/phase manipulation, − and optoelectronic/optoacoustic conversion. , Owing to the development of nano-/microfabrication techniques such as e-beam lithography (EBL), focused ion beam (FIB) milling, and so on, complicated nanostructured devices with ultranarrow linewidths and ultrahigh depth-to-width ratios have been achievable in recent years. , However, the fabrication of these devices using such precision techniques is time-consuming and of high costs, which limits the research and applications of these nanostructured devices, especially for large-area circumstances. In recent years, the anodic aluminum oxide (AAO) membrane with regularly hexagonally latticed pores has aroused great interest for its simple and efficient preparation process, which has been investigated widely and developed in many areas including producing nanotubes, transferring patterns, − and observing quantum confinement effects . A systematic, comprehensive, and deep research on the fabrication of the AAO membrane has been carried out by Lee et al, and two-dimensional single-layer plasmonic arrays have been obtained through the AAO membrane to excite the localized surface plasmon resonance. , However, dielectric arrays using the AAO template with materials like oxides and sulfides are lacking.…”
