Acquiring information carried by light / photons is crucial for fundamental studies of information science as well as many applications of light at both quantum and classical level. In this talk, I will present some recent work on scan-free direct measurement techniques that offers possibilities in characterizing high-dimensional photon systems in real time. We demonstrate these techniques by measuring orbital angular momentum of light, the complex spatial state of photons as well as the density matrix of a mixed photon state. We also extend the direct measurement concept to the classical region with an example of measuring a 3-D incoherent scene in a single shot. Lastly, I will present some works on function metamaterials that can potentially impact next-generation of optical metrology technologies. Zhimin Shi was born in Hangzhou, China. He received his Ph.D. degree in Optics from the University of Rochester in 2011. Before that, he received his Bachelor and M.S. degree, both with honors, from Zhejiang University in 2001 and 2004, respectively. Dr. Shi is currently holding the position of Assistant Professor at the Department of Physics, The University of South Florida. His research interest falls in the general area of quantum nonlinear photonics. His recent research topics include quantum state metrology, quantum information science, slow and fast light, metamaterials, nonlinear plasmonics, and optical techniques using nonclassical nature of light.
