Northwestern University researchers have developed compact, mid-infrared laser diodes that generate more light than heat – a breakthroughs in quantum cascade laser efficiency.
The results are an important step toward use of quantum cascade lasers in a variety of applications, including remote sensing of hazardous chemicals.
The research, led by Manijeh Razeghi, the Walter P. Murphy Professor of Electrical Engineering and Computer Science at the McCormick School of Engineering and Applied Science, was published online in the journal Nature Photonics on Jan. 10.
