SBIR Phase I: 3-D Photonic Band Gap Materials and Devices from Self-organized Anodic Alumina with Modulated Morphology

这个小企业创新研究（SBIR）第一阶段项目旨在开发和商业化新型3D微光子材料和可见光谱器件。尽管在过去的十年中对光子带隙材料进行了大量的研究，但在可见光区域创建能够结合高性能和低成本制造性的全3D光子晶体的方法仍然是一个很大程度上无法实现的目标。这种突破性的方法是通过一种独特的能力来精确调节高度有序的纳米多孔氧化铝的垂直孔结构，这不仅可以在平面上限制光，而且可以在三维上限制光。该过程将允许调谐材料的光子特性，特别是带隙，到所需的水平。在纳米多孔晶格内沉积材料的一些创新技术将提供结构折射率的横向和纵向修改。这一点，再加上对所得结构进行微机械加工的能力，将能够为光通信和计算创造先进的微光子和光电子设备和组件。提出的技术可能导致创建密集的单片光子和光电子元件和电路，用于非常高速的光学计算和通信。

This Small Business Innovation Research (SBIR)Phase I project seeks to develop and commercialize novel types of 3D microphotonic materials and devices for the visible spectrum. Despite the significant amount of research performed on photonic bandgap materials in the past decade, an approach to create full 3D photonic crystals in the visible region that could combine high performance with low cost manufacturability has remained a largely unobtainable goal. This breakthrough approach is enabled by an unique ability to precisely modulate the vertical pore structure in highly ordered nanoporous alumina, which can allow the confinement of light not just in-plane, but in 3 dimensions. The process will allow tuning of the photonic characteristics of the material, in particular the bandgap, to the desired levels. Several innovative techniques to deposit materials inside the nanoporous lattice will afford both lateral and vertical modification of the refractive index of the structure. This, combined with the ability to micromachine the resulting structures, will enable the creation of advanced microphotonic and optoelectronic devices and components for optical communications and computing.The techniques proposed could lead to the creation of dense monolithic photonic and optoelectronic components and circuits for very high speed optical computing and communication.
