Our research group is actively engaged in emerging fields including PCM-based temperature-tunable dynamic optical filters and absorbers, advanced terahertz (THz) photonics and optical device design, SPR-based biosensing platforms, and the radiation modeling and optimization of next-generation X-detector structures. We also work extensively on SCAPS-driven numerical analysis for high-performance solar cell architectures. Our efforts combine theoretical modeling, computational simulation, and device-level optimization to advance innovative photonic, sensing, and energy-conversion technologies. The group aims to establish a comprehensive platform for simulation-driven design and multidisciplinary research in modern optoelectronic and photonic systems.

SAFAYAT-AL IMAM (Member, IEEE) received his B.Sc. degree in Electrical and Electronic Engineering (EEE) from Ahsanullah University of Science and Technology (AUST), Dhaka, Bangladesh, in 2008, and his M.A.Sc. degree in Electrical and Computer Engineering (ECE) from Concordia University, Canada, in 2013. He completed his Ph.D. in Electrical and Electronic Engineering from Bangladesh University of Engineering and Technology (BUET) in 2025. Since 2014, Dr. Imam has been serving as an assistant professor in the Department of EEE at AUST. He has published numerous articles in national and international IEEE-sponsored conferences and various high-indexed journals. His research focuses on nanophotonics, 2D-material-based optoelectronic devices, SPR-enabled biosensing platforms, and phase-change-material (PCM)–driven tunable optical systems. He also works on advanced terahertz (THz) photonics and the modeling and optimization of next-generation X-ray detector architectures. In addition, he also applies SCAPS-based numerical modeling to develop advanced solar-cell architectures, coupling theoretical, computational, and device-level analyses.
