Mikhail Belkin, assistant professor in the Department of Electrical and Computer Engineering, was awarded for his work on "Terahertz Semiconductor Laser Sources for Operation Above Cryogenic Temperatures." The objective of his research is to investigate and develop widely and continuously tunable terahertz quantum-cascade lasers and other active devices based upon monolithic and voltage tunable metamaterial waveguides. The demonstration of amplifier and distributed feedback configurations will allow the output power to be scaled to several milliwatts or greater with a directive beam pattern. The broader impacts of his research lie in the development of a new approach for achieving tunable semiconductor lasers. Additionally, terahertz technology requires improved sources and detectors for sensing, imaging and spectroscopy.
