The Semiconductor Diode Laser Group at the College of Optics and Photonics (CREOL), University of Central Florida (UCF), invites applications for one or two Postdoctoral Research Associate or Research Scientist positions in nonlinear dynamical systems, numerical modeling, and synchronization of coupled oscillator networks. The project investigates emergent synchronization and collective dynamics in large networks of delay-coupled nonlinear oscillators, using…

A Postdoctoral/Research Scientist/Engineer position is available in the field of experimental optics and lasers. The University of Central Florida (UCF) is undergoing rapid growth in the size of external research funding, academic stature, and student and faculty groups. UCF supports and benefits from economic growth in Central Florida, which is emerging as a major hub…

A new Journal article has been published in Optics letters. Title: Phase-locking and brightness enhancement of a broad-area blue laser diode array Authors: Phase-locking and brightness enhancement of a broad-area blue laser diode array Abstract: Phase-locking of a QCW-operated broad-area blue laser diode array is demonstrated with 18.8 W peak power and 87.7% visibility via a…

Our work was presented at the Conference on Lasers and Electro-Optics (CLEO) on May 8 2025, in Long Beach, California. We showcased our latest experimental results in phase locking of broad-area blue laser arrays emitting at blue wavelength

A new Postdocoral Scholar, Sumit Singh, has joined the Braiman group. Sumit earned his B.Sc. in Physics at the University of Delhi and his M.Sc. in Physics at IIT Guwahati. He obtained his Ph.D. from Kyoto Institute of Technology, Japan, as a MEXT scholar, with research focused on materials science and optics, particularly structured light…

Luis Maldonado-Castillo has been accepted into the graduate program. Congrats Luis! We look forward to continuing our partnership.
