| Manijeh Razeghi Receives Jan Czochralski Gold Medal
McCormick Engineering News/ Amanda Morris - September 12, 2016
Northwestern Engineering’s Manijeh Razeghi has received the Jan Czochralski Gold Medal from the European Materials Research Society. The award recognizes her life achievements in the field of advanced materials science.
An expert in quantum devices, Razeghi will be presented with the award and will deliver a plenary talk at the Society’s fall meeting on Wednesday, September 21 in Warsaw, Poland.
“It took decades for the scientific community to recognize the importance of Jan Czochralski’s work,” said Razeghi, Walter P. Murphy Professor of Electrical Engineering and Computer Science in Northwestern’s McCormick School of Engineering. “On the 100th anniversary of his discovery, I am particularly proud to receive this award for my contributions to semiconductor quantum materials and devices. We can see the results of Czochralski’s science in almost every electronic and photonic device that we encounter. Even the first light-emitting diode would not have been successful without the high-quality substrates produced with the Czochralski Method.”

| Widely tunable MIR QCL eyed for spectroscopy, chemical sensing
flhotonlcs Spectra 29 - August 15, 2016
A broadband-tunable IR laser has demonstrated the ability to capture the unique spectral fingerprints of gases. The monolithic laser technology is compact, and is expected to have applications in spectroscopy and chemical sensing.
The laser only has one moving part-a fan for cooling purposes -which Northwestern University professor Manijeh Razeghi cited as a major advantage over existing systems. Most such lasers require mechanical parts to achieve tuning. It operates in the 6.2-to 9.1-µm wavelength range with a single emitting aperture by integrating an 8-laser sampled grating distributed feedback laser array with an on-chip beam combiner, and its gain medium is based on a 5-core heterogeneous quantum cascade laser wafer. ...

| Tunable Lasers to Revolutionize Infrared Spectroscopy
McCormick Press Release - June 8, 2016
A new development from Northwestern Engineering’s Manijeh Razeghi could be another tool for protecting our borders.
Supported by the Department of Homeland Security, Razeghi’s lab has created a new, revolutionary, broad-band tunable infrared laser that has major implications for the detection of drugs and explosives. The robust, all solid-state laser can be rapidly tuned to emit in the wavelength range that encompasses the critical “fingerprint” region where most molecular features are absorbed and identified through infrared sensing. In experiments, the laser has demonstrated its ability to capture the unique spectral fingerprint of gases. The initial, patent-pending results have been published in the June 8 issue of Nature Scientific Reports. The research and development of the laser system is the culmination of more than 18 years of quantum cascade laser development work at Northwestern’s Center for Quantum Devices. ... [read more]
