Meeting ID: 955 3053 1512 Passcode: 691285
Abstract:
Light-Matter Interaction plays critical roles in many photonics devices. In this seminar, I will discuss two approaches to enhance light-matter interaction, i.e., surface plasmonic resonance and optical antenna, as well as their applications in achieving high performance mid-IR and longwave IR photodetectors and FPAs. Device working principles and the enhancement mechanism through engineering electromagnetic fields will be presented.
Biography:
Dr. Xuejun Lu is a Professor in the Department of Electrical and Computer Engineering of University Massachusetts Lowell (UML). He received his PhD degree in Electrical Engineering from the University of Texas Austin in 2001. He worked as a postdoctoral research fellow at the microelectronic research center, UT Austin from 2001 to 2002 and a Senior Engineer at Finisar from 2002 to 2003. He joined the department of Electrical and Computer Engineering of University Massachusetts Lowell as an assistant professor in 2003. He was promoted to Associate Professor with tenure in 2008 and full professor in 2013. His research interests include: Surface plasmonics and optical antenna enhanced mid-wave and longwave infrared (MWIR/LWIR) photodetectors and focal plane arrays (FPA), Multi-color (band) IR sensors; Flexible thin-film transistors; Stand-off remote chemical sensor; Optical antenna enhanced avalanche photodiode (APD), Optical antenna induced strong light-matter interaction, Single quantum dot emitters; LWIR Electro-optic modulators based on intersubband transitions; High-quality ultra-uniform quantum dot and III-V material growth techniques.
The Seminar is open to the public free of charge.
