Talk Title: Manipulating Light with Novel Optical Materials and Structures

Abstract: Manipulation of light is of great importance for both research and industrial applications. It is realized through the interaction between light and matter. Therefore investigation of the interaction mechanism and design of novel optical materials and structures have become a vital part of scientific and engineering research. Here I will demonstrate my discoveries of the first visible light negative refraction, 3-dimensional deep-subwavelength optical cavity and extraordinary optical transmission based on different categories of novel optical materials, including metamaterials, naturally formed 2D structures. On the other hand, conventional materials with innovative structural designs can also provide new opportunities. I will discuss my work on silicon nanostructures that greatly improved the light trapping capability for energy harvesting purposes. Novel designs of optical materials and structures are enhancing our understanding of light–matter interaction mechanism and leading to new applications of light manipulation.

Biography: Jie Yao is a Postdoctoral Researcher in the Materials Science and Engineering Department at Stanford University. He holds a PhD in Applied Science and Technology from UC Berkeley. His research interests include metamaterials design and applications, light management for energy conversion, optomechanics and optical nano-cavities. He has demonstrated for the first time the negative refraction of visible light in bulk metamaterials, which promotes the research of metamaterials and potential applications such as invisible cloaks. He also designed and demonstrated the world's smallest three-dimensional indefinite optical cavities. His work was among the top 10 scientific discoveries of the year 2008 selected by TIME magazine.
