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 numerous peer review publications in journals such as Nature Photonics, Optics Express, Applied Physics Letters, Optics Letters and others. His papers has been cited over 900 times by other authors.

Experience: High-power laser beam combining, Volume Bragg gratings, High-power diode and fiber laser systems design and construction, Spectral narrowing of laser systems, Fabrication of ultra-selective volume Bragg gratings, Volume phase masks, Femto-second two-photon processes, Raman scattering in optical fibers, Electron beam lithography and nano-fabrication.
