Volker J. Sorger
|Address:||Science & Engineering Hall
800 22nd Street, NW
Professor Volker Sorger's research team investigates atto-Joule opto-electronics devices, optical information processing and computing, and smart IoT technologies. They follow an interdisciplinary approach that draws expertise from electrical engineering, materials science, and physics. They work to answer key fundamental questions in information processing and logic and bridge these with National Grand Challenges relating to reverse engineering the brain, enhancing virtual reality, and the Materials Genome Initiative. They are cross-pollinators with a core in nano opto-electronics. Our capabilities range from high-speed opto-electronic device fabrication and tests and novel materials integration, to IoT prototyping, and simulation and analysis. Recent demonstrations include the world's smallest laser, ultra-fast optical transistors for future photonic integrated circuits, and a solar-battery storage model. Profesor Sorger is director of the Orthogonal-Physics-Enabled-Nanophotonics (OPEN) Lab at GW.
