Researchers showcased their groundbreaking work to create light without heat and save significant energy during the Center’s 4th Annual Review Conference held on campus in November. About 130 participants including industry investors, sponsors and visiting researchers from throughout the United States, Asia, Europe and the Middle East as well as faculty and students listened as researchers presented the latest updates on their work.

“The Department of Energy expects that there will be a 50 percent reduction in high power needs in lighting with $250 billion in savings. That’s equal to 50,000 megawatts of power in the U.S. This research truly has the ability to transform the world,” said UCSB Vice Chancellor for Research Joseph Incandela.

Among the conference presenters ECE alumna Srabanti Chowdhury, associate professor in Electrical and Computer Engineering at UC Davis, is developing solutions for next generation electronics. All electronics including lighting, air-conditioning, computers and motion control devices rely on energy conversion in order to operate. Her research focuses on the use of diamond, gallium oxide and gallium nitride materials for next generation power and other emerging electronics to reduce the energy wasted as heat during conversion. “We’ve had big milestones that prove that diamond is a promising candidate,” Chowdhury said. “It has challenges, but we are seeing development from when I first started this work. Diamond’s performance is solid.”

In addition to Chowdhury, other researchers including Nakamura, DenBaars and Mishra presented their latest findings on laser lighting; green and UV LED lighting; and LiFi technology, high speed networked wireless communication, among other projects.
