Biography
Ivan Divliansky is currently a Group leader at the College of Optics and Photonics – CREOL at UCF. His current research interests include high-power laser beam combining, diffractive phase elements, diode and fiber lasers systems design, and implementation of volume Bragg gratings in different photonics areas.
Dr. Divliansky graduated with a Ph.D. in Electrical Engineering /Materials Science from The Pennsylvania State University in 2004 performing research related to photonic crystals and their fabrication using holography and nano-fabrication. Before that he earned his B.S. and M.S. from the Physics department of Sofia University, Bulgaria. His M.S. thesis research focused on stimulated Raman processes in optical fibers.
Dr. Divliansky has authored one book chapter, co-authored three patents, is an Editorial Board member of the Journal of Lasers, Optics & Photonics and also frequent referee for Optics Express, Optics Letters, Applied Optics, and other peer review journals. His papers have been cited over 1000 times by other authors.
