[edit] Education and Honors
Dr. Claire F. Gmachl earned her M.Sc. in Physics from the University of Innsbruck in 1991. She went on to receive her Ph.D. in Electrical Engineering from the Technical University of Vienna in 1995, graduating sub auspiciis Praesidentis (with special honors by the president of the Austrian republic). Her studies focused on integrated optical modulators and tunable surface-emitting lasers in the near infrared. From 1996 to 1998, she was a Post-Doctoral Member of Technical Staff at Bell Laboratories, the famous research division currently run by Lucent Technologies. In 1998, she became a formal Member of Technical Staff at Bell Labs and in 2002 she was named a Distinguished Member of Technical Staff, in part due to her pioneering work on the quantum cascade laser. However, in 2003, she left Bell Labs and took a position as Associate Professor in the Department of Electrical Engineering at Princeton University, where she is currently working.
In 2004, Popular Science named her to its "Class of 2004 - Brillaint 10," its list of the 10 most promising scientists under 40. She went on, in September 2005, to win the MacArthur Foundation's "genius grant." Recently, she was named the director of the new Mid-Infrared Technologies for Health and the Environment (MIRTHE) Center, funded by the National Science Foundation.
[edit] Research
Although Dr. Gmachl originally intended to study theoretical applied mathematics, her interest soon turned to theoretical applied physics, and, with the encouragement of an advisor, experimental sciences.
Dr. Gmachl is an experimental scientist working at the intersection of technology and fundamental physics in the fields of optics and semiconductor laser technology. A wizard at imagining and creating new designs for solid-state lasers, Gmachl’s pioneering work has led to critical advances in the development of Quantum cascade lasers. QC lasers are a rapidly evolving class of high-performing, mid-infrared, semiconductor light sources. The lasers designed by Gmachl and her colleagues are noteworthy for their considerable wavelength tunability, high-power operation, high-speed modulation capabilities, and seemingly unlimited design potential. She has demonstrated the versatility and promise of mid-infrared light sources for a wide range of applications, including trace gas sensing in the environmental, industrial, and medical fields, and free-space optics in wireless communications. Her recent achievements include the development of QC microlasers and new hybrid devices, which include quantum cascade structures and nonlinear components, dramatically extending the wavelength range of QC technology. These designs have direct applications to environmental monitoring, clinical diagnoses, spectroscopy, and chemical process control. With her combination of technological flair and deep understanding of physical concepts, Claire Gmachl translates complex principles into original and practical devices that advance our understanding of optical device designs and promise to address a wide variety of engineering challenges.
