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

这个小型企业创新研究(SBIR)第一阶段项目致力于开发和商业化用于可见光光谱的新型3D微光子材料和设备。尽管在过去的十年里对光子带隙材料进行了大量的研究，但在可见光区域制造能够结合高性能和低成本可制造性的全3D光子晶体的方法在很大程度上仍然是一个无法实现的目标。这种突破性的方法是由于一种独特的能力，可以精确地调制高度有序的纳米多孔氧化铝的垂直孔结构，这不仅可以限制光的平面内，而且可以限制光的三维。这一过程将允许将材料的光子特性，特别是带隙，调整到所需的水平。在纳米多孔晶格内沉积材料的几种创新技术将提供对结构折射率的横向和垂直修改。这一点，再加上微机械加工所产生的结构的能力，将能够创造出先进的微光和光电子器件和组件，用于光通信和计算。所提出的技术可能导致制造用于超高速光计算和通信的致密单片光子和光电子组件和电路。

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.
