Reporter's CV:

Prof. Sergey Ponomarenko, Department of Electrical and Computer Engineering, Dalhousie University, Halifax, NS, B3J 2X4 Canada. Sergey Ponomarenko earned his Ph.D. degree in theoretical optical physics from the University of Rochester, USA under the tutelage of Prof. Emil Wolf, a founder of classical optical coherence theory. Prior to joining Dalhousie University, Canada as a tenure-track faculty and a Canada Research Chair in 2006, Dr. Ponomarenko had held a Director’s Postdoctoral Fellowship at Los Alamos National Laboratory, USA from 2004 to 2006. In 2010, Dr. Ponomarenko was promoted to Associate Professorship and his Canada Research Chair award was renewed. In his spare time, Dr. Ponomarenko tries to understand better fundamental aspects of optical coherence theory, nonlinear statistical optics and plasmonics with his graduate students and postdocs. He also enjoys track and half-marathon running, weight training, and an occasional badminton game among other sports activities.


I will start with a brief introduction to classical optical coherence theory outlining the physical interpretation of classical coherence as well as measurement procedure(s) and theoretical description of statistical light sources within the framework of second-order optical coherence theory. I will then proceed to present selected results of my group’s work on generating partially coherent light beams and pulses with nontrivial coherence properties tailored to promising applications. In particular, I will discuss dark and anti-dark diffraction free beams, optical coherence lattices, and pulses comprised of uncorrelated nonorthogonal coherent modes.
