Research highlight: Better than X-rays: A more powerful terahertz imaging system
An electrical engineering research team at the University of Michigan has developed a laser-powered terahertz source and detector system that transmits with 50 times more power and receives with 30 times more sensitivity than existing technologies. This offers 1,500 times more powerful systems for imaging and sensing applications.
This work was led by Prof. Mona Jarrahi, the director of Terahertz Electronics Laboratory at the University of Michigan and the results are published in the March edition of Nature Communications “Significant performance enhancement in photoconductive terahertz optoelectronics by incorporating plasmonic contact electrodes”. Dr. Mehmet Unlu, who has recently joined the Electronics and Communication Engineering Department of our university, was a part of this study when he was a postdoctoral scholar in the Terahertz Electronics Laboratory at the University of Michigan. The other authors include: Christopher Berry, Ning Wang, and Mohammad Reza Hashemi from the Terahertz Electronics Laboratory at the University of Michigan.
