Welcome to Zongfu Yu's home page

I am a postdoc researcher in Ginzton Lab, Stanford Unviersity.
I got my B.S. in physics from University of
Science and Technology of China in 2004 and Ph.D in applied physics from
Stanford University in 2009
I work in Shanhui Fan's
group in Ginzton Lab. My phd research is focused on micro-scale optical isolator
and plamonics devices(in collaboration with Prof. Brongersma)
I explored the unique light controllability enabled by dynamic photonic structures. Very recently, I got interested
in photovoltaic solar cells. I believe that there are promising opportunities using nanophotonic
design for cost reduction and
efficiency improvement.
