Prof. Zetian Mi has been elected Fellow of OSA, the Optical Society, “for contributions to the development of high performance III-nitride nanowire photonic devices, including full-color light emitting diodes, electrically injected ultraviolet lasers, and artificial solar fuel technology.”

He researches semiconductor optoelectronics, specifically III-nitride semiconductors, low dimensional nanostructures, LEDs, lasers, Si photonics, artificial photosynthesis and solar fuels. Examples of recent work include sustainable energy through artificial photosynthesis, and biochemical purification, sensing, communication and lighting applications through the lithography-free fabrication of nanowire array lasers.

Prof. Mi is Co-chair of the 11th International Symposium on Light Emitting Devices (ISSLED 2017). He has received the Young Scientist Award from the Int. Symp. on Compound Semiconductors and the Young Investigator Award from the 27th North American Molecular Beam Epitaxy Conference.

An alumnus of Michigan, Mi received his Ph.D. in Applied Physics in 2006. He returned as a faculty member in 2016. Most recently, he was an Associate Professor of Electrical and Computer Engineering at McGill University, where he received several major awards including the Engineering Innovation Award. He also worked at Picometrix, Inc. from 2001 to 2003, a local company spun out of the U-M College of Engineering Center for Ultrafast Optical Science.

About OSA Fellows

EnlargeOSA logo

OSA‘s mission is to promote the generation, application and archiving of knowledge in optics and photonics and to disseminate this knowledge worldwide. Fellows are members who have served with distinction in the advancement of optics and photonics. Only 10% of OSA membership may be fellows, and the number elected each year is typically limited to 0.5% of membership.

OSA was founded in 1916, and is the leading professional organization for leaders in the field of the science of light, including students, engineers, scientists, and those in business.

3301 EECS

The electrons absorb laser light and set up “momentum combs” (the hills) spanning the energy valleys within the material (the red line). When the electrons have an energy allowed by the quantum mechanical structure of the material—and also touch the edge of the valley—they emit light. This is why some teeth of the combs are bright and some are dark. By measuring the emitted light and precisely locating its source, the research mapped out the energy valleys in a 2D crystal of tungsten diselenide.

Mapping quantum structures with light to unlock their capabilities

Rather than installing new “2D” semiconductors in devices to see what they can do, this new method puts them through their paces with lasers and light detectors. | Medium Read
