Global internet is growing at a compound rate of 24% per year, reaching 3.3 zettabytes per year by 2021. High-speed optical communication is urgently needed in this ever-connected world, and to keep up with this growth, developments in the fabrication of optical transceivers are sorely needed. Ph.D. candidate Xiao Liu, of the TU/e Department of Electrical Engineering, researched new ways to integrate the electronic circuits and photonic devices that make up optical transceivers. He will defend his Ph.D. thesis on 1 December 2020.
