Congratulations to Curtis Wang on winning the prestigious DoD NDSEG fellowship! We look forward to his work on the transistor laser and VCSEL. See the department article here for more details: http://illinois.edu/lb/article/1076/92414
Link to the Past
In 1976, Prof. Feng was a graduate student for G.E. Stillman, where he conducted LPE growth and fabricated 1.3 um InGaAsP/InP detectors. Our department found a photo of him working hard:

Optical Society of America Awards R.W. Wood Prize to Prof. Milton Feng
Congratulations to Professor Feng and all past and current members of the HSIC group for this award! Overall, the HSIC group has been awarded 16 patents and has published over 50 papers on the light-emitting transistor and transistor laser. Professor Feng would like to thank all former and current HSIC group members for their efforts.
850nm Oxide-Confined VCSEL with 40 Gb/s Error Free Data Transmission
Congratulations to Dr. Fei Tan, Mong-Kai Wu, and Michael Liu for their spectacular efforts in developing an oxide-confined VCSEL that can transmit 40 Gb/s error free data rate. This device is the fastest directly modulated laser (not using a peaked driver circuit) in the United States

50th Anniversary of the LED
The October 2013 issue of Proc. IEEE features the 50th anniversary of the LED. Take a look at this issue, featuring articles by great Illinois alumni like Nick Holonyak, George Craford, Russ Dupuis, Fred Kish, John Dallesassee, Dennis Deppe, John Rossi, Joy Laskar, Han Wui Then, and Milton Feng. Of course other non-Illinois alumni are featured as well (Kroemer, Alferov, Iga, Kumagai, Nakamura), and this issue is chock-full of the illustrious history of light-emitting semiconductors. Highly recommended!
Congratulations to Mong-Kai Wu for Cover of Applied Physics Letters
Congratulations to Mong-Kai Wu for his paper, “Voltage modulation of a vertical cavity transistor laser via intra-cavity photon-assisted tunneling,” which was placed on the cover of Volume 101, Issue 8 of Applied Physics Letters.

Congratulations to Donald Cheng: Best Student Paper at CSMANTECH
Congratulations to Dr. Donald Cheng for winning Best Student Paper at CSMANTECH 2011 for his paper titled, “Type-II DHBTs Microwave Characterization and Metallization Issues”. This paper described the problem of emitter-to-base shorts during the fabrication of Type-II submicron DHBTs. He presented designs of experiment to identify the problem, as well as the solution to the problem. Ultimately, the BE shorts were minimized, and devices were fabricated with room temperature current gain cutoff frequency (fT) up to 680 GHz.
Transistor Laser is in the News
Two great new articles on the transistor laser were published this month!
From Compound Semiconductor: “The Transistor Laser: A Radical, Revolutionary Device”
and from Optics and Photonics News: “The Metamorphosis of a Transistor into a Laser”
HKUST Webcast Lecture on Transistor Laser
Professor Feng gave an invited lecture on the transistor laser at the Hong Kong University of Science and Technology’s Institute for Advanced Study. He covers the history of its invention, the basic physics of operation, current research results, and future expectations for the novel device.
