HAMED TARI

I am a researcher specializing in neurophotonics and integrated optical circuits, currently working as a Research Fellow in the “Photonic Technologies and Artificial Intelligence” research line at the Centro Ricerche Enrico Fermi (CREF). My academic journey is deeply interdisciplinary, beginning with a BSc in Applied Chemistry and an MSc in Nanochemistry focusing on nanosensors in Iran, before moving to Italy to complete an MSc in Nanotechnology Engineering and a PhD in Electromagnetics and Nanosciences at Sapienza University.

My research lies at the intersection of optical computing, materials science, and artificial intelligence. I am deeply motivated by the need to overcome the physical limitations and high energy demands of traditional electronic computing. During my PhD, I designed and developed optical building blocks for neuromorphic Photonic Integrated Circuits (PICs), utilizing photorefractive plasticity, optical solitons, and surface plasmon polaritons (SPP) to create artificial neural synapses. My skills span the development pipeline, from numerical simulations using COMSOL and Python to hands-on optoelectronic device fabrication and nanomaterial synthesis.

Currently, as part of the Computational Photonics Laboratory at CREF, my work focuses on designing the Coherent Photonic Extreme Learning Machine (CPELM) for complex state classification tasks. In alignment with our group’s mission to build energy-efficient optical computing hardware, we develop innovative stabilized interferometric schemes optimized for physical precision and energy efficiency.
