C.J. Chang-Hasnain, Laser Engineering Luminary, to Receive 2011 IEEE David Sarnoff Award

Pioneering Contributions Have Led to Widespread Deployment of Vertical Cavity Surface Emitting Lasers

22 February 2011 – C.J. Chang-Hasnain, an engineer whose groundbreaking contributions to the physics and design of Vertical Cavity Surface Emitting Lasers (VCSELs) have shaped their use in modern technology, is being honored by IEEE with the 2011 IEEE David Sarnoff Award. IEEE is the world’s largest professional association advancing technology for humanity.

The award, sponsored by Sarnoff Corporation, recognizes Chang-Hasnain for pioneering contributions to VCSEL arrays and tunable VCSELs. The award will be presented on 8 March 2011 at the Optical Fiber Communication Conference and Exposition/National Fiber Optic Engineers Conference in Los Angeles, Calif.

Chang-Hasnain’s seminal contributions have been instrumental in establishing VCSELs as the dominant technology for multimode fiber applications. And her work has had a profound influence on commercial tunable, high-speed and laser array designs. VCSELs comprise more than 75 percent of today’s laser market, dominating the high-volume, low-cost and short-distance laser sectors. They can be turned on and off very fast, at billions of times per second, but yet manufactured at very low cost in wafer-scale. VCSELs are now used in applications ranging from Ethernet data networks to computer mice to laser printers. Most local area networks and large-scale data centers supporting Internet traffic use VCSELs. Active optical cables that link home high-definition television components are a growing consumer application of VCSELs.
