About

Deen Gu is an emerging researcher specializing in neuromorphic computing, optoelectronic synaptic devices, and artificial visual systems — fields at the exciting intersection of photonics, materials science, and brain-inspired computing. His work centers on developing silicon-based and oxide-based devices that mimic biological synapses, enabling machines to process visual information in ways that closely parallel human perception. Gu's most influential contribution, "Color-Recognizing Si-Based Photonic Synapse for Artificial Visual System" (2020), has garnered 45 citations and addressed a critical challenge in neuromorphic engineering: building synapses capable of directly responding to light signals for use in neuromorphic chips and artificial vision systems. This foundational work set the stage for his subsequent research, including an oxide-based heterojunction optoelectronic synaptic device offering wideband and rapid response capabilities (2022, 19 citations), and an enhanced broadband Si-based optoelectronic synapse (2022, 9 citations). His most recent work on integrated optoelectronic memory arrays achieves an impressive 99.64% recognition accuracy under near-infrared conditions, pointing toward transformative applications in robotic vision. Together, Gu's publications demonstrate a clear and ambitious research trajectory — steadily advancing the practical realization of high-performance, light-driven artificial intelligence systems.
