Dr WANG Cheng, Assistant Professor, has published the journal paper “Integrated lithium niobate electro-optic modulators operating at CMOS-compatible voltages” in Nature on 24 September 2018.
Nature is regarded as one of the world's top academic journals and the world's most cited scientific journal. It is so excited that Dr Wang is our first EE faculty member having paper published in Nature.
The outstanding paper can be found at https://www.nature.com/articles/s41586-018-0551-y. To give you a glimpse of the research work, here is a quote from the abstract: Here we overcome these limitations and demonstrate monolithically integrated lithium niobate electro-optic modulators that feature a CMOS-compatible drive voltage, support data rates up to 210 gigabits per second and show an on-chip optical loss of less than 0.5 decibels. We achieve this by engineering the microwave and photonic circuits to achieve high electro-optical efficiencies, ultra-low optical losses and group-velocity matching simultaneously.
