Sangyoon Han Berkeley’s Sangyoon Han and Tae Joon Seok are among the 2015 finalists in the Graduate Division of the 2015 Collegiate Inventors Competition (CIC). Sangyoon Han, a Ph.D. candidate in the Department of Electrical Engineering and Computer Sciences (EECS) focuses his research on implementing optoelectronic devices on Silicon Photonic platform using MEMS technologies. Tae Joon Seok Tae Joon Seok is a postdoctoral researcher in EECS in Professor Ming Wu’s group. He received his B.S. degree from Seoul National University, Korea, in 2007 and his Ph.D. from Berkeley in 2012 in Electrical Engineering. His research interest has been in the area of plasmonics, nanophotonics, and Si photonics. Their invention SWAPS (Silicon Waveguide Array Photonic Switch) is an Energy-Efficient Cloud. SWAPS, a thumb-sized gadget, allows for full use of a data center’s bandwidth capacity by actively re-arranging the network pattern of “the cloud.” While we might be saving trees because the need to print photos and documents has declined, “the cloud” is growing fast and storing and accessing files or websites consumes energy. They will showcase their invention at the CIC Expo (think “science fair for college students”) on November 17, 2015, in Alexandria, Virginia. Winners will be announced at an awards ceremony immediately following. Graduate and undergraduate winners and their advisors will be awarded a total of $100,000 in cash and prizes. Founded in 1990, the Collegiate Inventors Competition recognizes and rewards the nation’s top collegiate inventors in partnership with the National Inventors Hall of Fame and the United States Patent and Trademark Office. Finalists will have the opportunity to present their research and prototypes to experts in the nation for real-world feedback on optimizing the potential of each invention.
