 Nano-photonic devices are playing increasingly important roles in optical interconnects and optical sensor systems. By engineering the nano-photonic structures, for example, by integrating surface plasmonic and photonic crystal devices on the same platform, we can significantly increase the light-matter interaction through localized electric fields and photonic bandgaps. In this presentation, I will discuss the development of innovative nanophotonic devices for two emerging engineering applications: 

1) Metallic-Photonic Crystals with integrated nonlinear polymers for high-speed optical interconnects and all-optical signal processing 

2) Surface-enhanced Raman scattering (SERS) sensors using biosilica photonic crystal materials for biomedical detection 


In addition, I will briefly introduce the on-going research in my group in the field of optical gas sensing using plasmonics enhanced metal-organic framework materials, and free-space optical communication to enhance the bandwidth of in-door WiFi systems. 

Speaker Biography 

Alan X. Wang is an Assistant Professor of the School of Electrical Engineering and Computer Science at Oregon State University. He received his B.S. degree from Tsinghua University, and M.S. degree from the Institute of Semiconductors, Chinese Academy of Sciences, Beijing, P.R. China, in 2000 and 2003, respectively, and his Ph.D. degree in Electrical and Computer Engineering from the University of Texas at Austin in 2006. From January 2007 to August 2011, he was with Omega Optics, Inc., Austin, Texas, where he served as the Chief Research Scientist with more than 4 million dollars of research grants from various government agencies, including the National Science Foundation (NSF), the Air Force Office of Scientific Research (AFOSR), the Defense Advanced Research Project Agency (DARPA), the Army Research Office (ARO), the Environmental Protection Agency (EPA), and National Institute of Health (NIH). He joined OSU as an assistant professor in August 2011. His current research activities are sponsored by NSF, NIH, Oregon Nanoscience and Microtechnologies Institute (ONAMI), the National Energy Technology Laboratory (NETL) of the Department of Energy (DoE), and industrial sponsors such as Hewlett Packard, and Marine Polymer Technologies. 


He has more than 50 journal publications and more than 50 conference presentations (including 9 plenary/invited presentations), and also holds four U.S. patents. He is a Senior Member of the Institute of Electrical and Electronics Engineers (IEEE), the Optical Society of America (OSA), and a member of the International Society for Optical Engineering (SPIE).
