Investigating Surface Plasmons and Photonic Bandgap of Ordered Nanoarray Constructed by Hierarchical Alumina Membranes — •Yi Wang, Yudie Huang, Jiaxu Chen, Fanzhou Lv, and Wenxin Wang — Photonic Materials Group, College of Physics and Optoelectronic Engineering, Harbin Engineering University, Harbin, China

The purpose to manipulate photonics and the trend of device miniaturization prompt people to design sophisticated ordered nanostructures with well practicability over large scale. Attributing to the inherent structure feature of ordered pore array, alumina membranes (AMs) are widely used in preparation of ordered nanoarrays for various device applications. For the reason that, artificial modulated AMs can offer porous membranes with uniform geometric parameters, in order to achieve controllable distribution of nanomaterials. Here, we demonstrate the idea to fabricate hierarchical alumina membrances (HAMs) with controllable subwavelength patterns as promising platform to construct plasmonic structures. By precisely controlling the anodization potential, sophisticated structures of AMs are regulated into distinctive patterns. After replicating HAMs with functional polymer and noble metal, hierarchical nanostructures (HNs) with unique surface plasmon resonance (SPR) properties are obtained, which is developed as dynamic plasmonic sensing device. In addition, the photonic bandgap brought by HNs are investigated in detail. This approach for elaborate HNs fabrication broadens the scope for the design and application of functional nanostructures in the field of nanophotonic devices.
