Danxia Xu: Silicon photonics for biosensing

Nanophotonic waveguides enable very small sensors with high response and high sensitivity.
26 June 2012, SPIE Newsroom. DOI: 10.1117/2.3201206.03

Dan-Xia Xu is a Senior Research Officer with the National Research Council Canada, and an adjunct professor with Carleton University. She received her PhD from Linköping University (Sweden) in 1991, working on silicon-germanium HBTs and tunneling diodes.

Since joining NRC, her work has encompassed high-speed SiGe HBTs, silicides for submicron VLSI, SiGe and silicide photodetectors, and integrated optics. In 2001-2002 she was part of the research team at Optenia Inc. that successfully developed the first glass waveguide echelle grating demultiplexer. She has been the coordinator of the Silicon Photonics Project since 2007. Her current research interest is silicon photonics, particularly nanophotonic devices for biological sensing and optical communications. She has co-authored over 250 publications in technical journals and international conferences, several book chapters, and holds seven patents.

She has served on the program committee for the annual conference on silicon photonics at SPIE Photonics West since its inception in 2006, and for its precursor conferences for several years before that. She has authored more than 40 papers presented at SPIE events.
