中文摘要： 对光进行控制一直是人类追求的目标。将纳米材料与光子学结合起来，是实现对光的控制的一个重要发展方向。本项目瞄准利用多孔阳极氧化铝光子晶体对光传输进行调控开展工作。拟采用电化学阳极氧化方法可控地制备出宏观尺度的具有光子晶体特性的多孔阳极氧化铝片，深入研究其制备规律，获得电化学阳极氧化过程中孔洞的生长速度，和电解液对孔洞的化学腐蚀速度，以及两者之间的匹配关系。在这种多孔阳极氧化铝片中引入缺陷，获得缺陷峰位置和高度均可调的多孔阳极氧化铝光子晶体，研究缺陷对光传输行为的影响。基于多孔阳极氧化铝光子晶体构筑光子晶体异质结，并在多孔氧化铝的孔道中引入其他介质，获得消光量可调的多孔氧化铝片，基于这种消光量可调的多孔氧化铝光子晶体异质结构筑具有光二极管特性的原理型器件，实现对光的选择性传输。此项研究有望将这种多孔阳极氧化铝光子晶体向实际应用推进。

英文摘要： Controlling light has always been the goal of the human pursued. Combination of nanomaterials and photonics is an important developing direction to realize the control on the light. This project is aimed at the control effect of the porous anodic alumina photonic crystal on the optical transmission. In this project, we intend to adopt the electrochemical anodic oxidation method to controllably prepare the macroscopic size of porous anodic aluminum oxide (AAO) slab that has the characterization of photonic crystal, in depth study the growth rate of nanoholes as well as the chemical corrosion rate of the nanohole by electrolyte during the electrochemical oxidation process, and obtained the quantitative relationship. Research the method of introducing defects into the porous AAO slab, and get the adjustable location and height of defect peak for porous AAO photonic crystals. Build the photonic crystal heterojunction based on the porous AAO photonic crystal, introduce the media into the nanoholes of the porous AAO, achieve the adjustable extinction amount, then basing on such photonic crystals heterojunction to build principle-based device with light diode characteristics, and thus realize the selective transmission of light. This study is expected to propel the porous AAO photonic crystal to the practical application.
