Abstract: The functionality of photonic integrated circuits (PICs) is rapidly increasing and is having a major impact on applications in timing, navigation and data communications. Photonics can reduce energy consumption in information processing and communications while simultaneously increasing the interconnect bandwidth density. With the use of photonic integration and fiber optics, and the elimination of electrical line charging dissipation, we can save integrated circuit power by transmitting data from 1 mm to 1 km with the same energy (20 fJ/bit) and simplicity as local electrical wires on chip. A focus of our research is on using quantum dot (QD) lasers and integration on silicon for lower threshold and higher efficiency sources, higher temperature operation, isolator free operation, and superior mode locking capability. A recent example includes a 4.1 Tbps, 60 wavelength, 32 Gbaud PAM-4 transmitter using a single mode locked quantum dot laser.
JOHN E. BOWERS holds the Fred Kavli Chair in Nanotechnology and is the Director of the Institute for Energy Efficiency and a Professor in the Department of Electrical and Computer Engineering. Dr. Bowers received his M.S. and Ph.D. degrees from Stanford University and worked for AT&T Bell Laboratories and Honeywell before joining UC Santa Barbara.
Dr. Bowers is a member of the National Academy of Engineering, a fellow of the IEEE, OSA and the American Physical Society, and a recipient of the OSA Holonyak Prize, the IEEE LEOS William Streifer Award and the South Coast Business and Technology Entrepreneur of the Year Award. He and coworkers received the ACE Award for Most Promising Technology for the hybrid silicon laser in 2007. Professor Bowers' research interests are in silicon photonic integrated circuits for the next generation of coherent optical systems.
