|Dr. WANG Qijie received the B.E. degree in electrical engineering from the University of Science and Technology of China (USTC), Hefei China, in 2001 graduating one year in advance; and the Ph.D degree in electrical and electronic engineering from Nanyang Technological University, Singapore, in 2005, with NTU and Singapore Millennium Foundation (SMF) scholarship. After completing his Ph.D, he obtained the 2005 SMF postdoctoral fellowship working in NTU. Then he joined School of Engineering and Applied Science, Harvard University, in Prof. Federico Capasso’s group as a postdoctoral researcher in Jan. 2007. During his postdoctoral studies at Harvard University, he has made significant contributions in achieving high-performance both mid-infrared and Terahertz quantum cascade semiconductor lasers. In October 2009, he was assigned as a joint Nanyang Assistant Professor at the School of Electrical and Electronic Engineering (Microelectronics Division) and the School of Physical and Mathematical Sciences (Physics and Applied Physics Division).
Dr. Wang has published/co-published about 80 papers (including 6 invited papers) in top international journals (like Nature Photonics, Nature Materials, and Nature Communications), more than 70 conference papers (including numerous invited talks) and co-authored 7 U.S. patents. He was the recipient of the top prize for the Young Inventor Awards of the SPIE Photonics Europe Innovation Village in 2004; a golden award from the Fifth Young Inventor’s Awards in 2005 organized by HP and Wall Street Journal; and the co-recipient of the IES (Institution of Engineers Singapore) Prestigious Engineering Achievement Team Award 2005 of Singapore.
|My current research interests are to explore theoretically and experimentally nano-structured semiconductor and fiber-based materials, and nanophotonic devices (nanoplasmonics, photonic crystals and metamaterials) with an emphasis on all aspects of the problem: from design, fabrication, characterization, to integration at system level.
In particular, I am going to investigate the fundamental properties (optical and electrical) of semiconductor (quantum cascade lasers) and high power fiber lasers, and nanophotonic devices (such as graphene optoelectronic devices) in the infrared frequency regimes (inclulding near-IR (~1.5um), mid-IR (~3-30 um) and Terahertz (~60-300 um)) to improve their performance. Exploration of their broad potential applications is also one of the key focuses.
We are always looking for strongly motivated both postdoc and Ph.D researchers dedicated to the cutting edge research in semiconductor and fiber lasers, nanotechnology, plasmonics and metamaterials, and nano-optics/photonics. Interested candidates please send your CV to email@example.com. Shortlisted candidates will be contacted.
Currently we have several postdoc positions available on the development of high performance fiber lasers and nanophotonics.
