Postdoctoral Research Associate in Nonlinear Computational Dynamical Systems

CREOL (Center for Research and Education in Optics and Lasers) is one of the world’s foremost institutions for research and education in optical and photonic science and engineering. The College offers MS and PhD degrees in optics and photonics, and a BS degree in photonic science and engineering. The faculty engages in fundamental and applied research and education in lasers, optical fibers, semiconductor and integrated photonic devices, nonlinear and quantum optics, imaging, sensing, and displays.

The college is home to theCREOL, Florida Photonics Center of Excellence (FPCE), and Townes Laser Institute (TLI), and the Institute for the Frontier of Attosecond Science and Technology (iFAST). In addition, the College of Medicine, which includes the Burnett School of Biomedical Sciences, provides rich opportunities for collaboration.

Applications are invited for a postdoctoral research position in computational nonlinear dynamics and large-scale numerical modeling of semiconductor laser arrays at the College of Optics and Photonics (CREOL), University of Central Florida. Our research program investigates collective dynamics, synchronization, and self-organization in large arrays of coupled semiconductor diode lasers. The work combines experiments with computational and theoretical modeling of nonlinear dynamical systems with time-delayed interactions.

A major objective of this position is to develop and implement efficient numerical methods for increasingly large and complex systems of coupled nonlinear delay-differential equations (DDEs). Models range from arrays of single-mode semiconductor lasers described by Lang–Kobayashi-type equations to substantially larger multimode systems incorporating multiple optical modes, carrier dynamics, nonlinear interactions, heterogeneity, and delayed nonlocal coupling. As the number of lasers and optical modes increases, direct numerical simulation becomes computationally demanding.

The successful candidate will therefore focus not only on physical modeling but also on developing, optimizing, and accelerating computational approaches capable of treating large laser networks efficiently.

The postdoctoral associate researcher will contribute to several areas, including:

• Numerical integration of large systems of nonlinear delay-differential equations
• Modeling of single-mode and multimode semiconductor laser arrays
• Optimization and acceleration of existing simulation codes
• Parallel computing and high-performance computing (HPC)
• GPU acceleration, where appropriate
• Development of scalable numerical algorithms for systems containing large numbers of lasers and optical modes

An important component of the project will be determining how numerical algorithms and existing stimulation codes can be redesigned or optimized to achieve substantial improvements in computational speed while preserving numerical accuracy and stability. The position provides an opportunity to work at the intersection of computational mathematics, nonlinear dynamics, high-performance computing, and experimental photonics. The research is closely connected with ongoing experiments involving large semiconductor diode laser arrays.

This interaction provides an unusual opportunity for computational researchers to test theoretical and numerical predictions against experimentally observed collective dynamics. This position allows for opportunities for interdisciplinary collaboration involving researchers in optics, photonics, nonlinear dynamics, applied mathematics, and computational science.

Semiconductor-laser experience is not required. The successful candidate will work closely with experimental researchers, and the necessary background…
