Associate Professor
Biography
Professor Yang joined the faculty at Washington University in St. Louis in 2007. She runs the Laboratory of Micro/Nano Photonics Research Group in the School of Engineering & Applied Science.
 
In 2010, she earned a National Science Foundation CAREER Award and in 2011, she was honored by President Barack Obama with a Presidential Early Career Awards for Scientists and Engineers (PECASE). The early career award is the highest honor bestowed by the United States government on science and engineering professionals in the early stages of their independent research careers.
Research
Professor Yang's research interests are fabrication, characterization, and fundamental understanding of advanced nano/micro photonic devices with outstanding optical properties. Currently, her group focuses on the silicon-chip based ultra-high-quality micro-resonators made from spin-on glass. The spin-on glass is a kind of glass obtained by curing a special liquid using sol gel or wet chemical synthesis to form a layer of glass. The main advantage of the spin-on glass is the easy tailoring of the nano/micro structure of the glass by controlled variation in the precursor solutions. It enables them to fabricate various micro/nano photonic devices from advanced materials with desired properties.
