Abstract:

Optofluidics is the combination of integrated optics with microfluidics on the same chip and presents a wealth of new opportunities for developing high-sensitivity labs-on-chip for fundamental science and analytical instruments. In this talk, I will describe how the development of planar hollow-core waveguides has enabled new avenues for analyzing liquids and gases in the convenient environment of a silicon chip. I will then illustrate how optofluidics can be used to define optical device properties, enable optical detection and optical particle manipulation. Specific examples will include on-chip pathogen detection with single virus resolution, new types of planar integrated optical traps and their applications, and the integration of nanopores for electro-optical detection of single nanoparticles.  

Bio:  

Holger Schmidt received his PhD in Electrical and Computer Engineering from the UC Santa Barbara in 1999. After spending two years as postdoctoral fellow at M.I.T., he joined UC Santa Cruz where is currently Associate Professor of Electrical Engineering and Director of the newly established W.M. Keck Center for Nanoscale Optofluidics. He has authored or coauthored over 150 publications and several book chapters in various field of optics. His current interests are in single particle optics, including single-photon nonlinearities, nano-magneto-optics, and single-molecule studies in optofluidic devices. He chaired the 2008 IEEE Summer Topical Meeting on Optofluidics and the Special Symposium on Optofluidics at CLEO 2009.   Dr. Schmidt is a member of the IEEE, the Optical Society of America and the American Physical Society. He was the recipient of a National Science Foundation CAREER Award in 2002 and a Keck Futures Nanotechnology Award in 2005.  

The seminar will be held in E001 Scott Laboratory.
