A team led by SYSU Professor Yu Siyuan and made up of researchers from Sun Yat-sen University and Fudan University in China and University of Bristol and University of Glasgow in the UK has conducted an innovative research in integrated photonics. Their work is highlighted on the cover of the current issue of Science on October 19, 2012 (http://www.sciencemag.org/journals), and selected as Editor’s Choice. This research explores a new frontier in integrated photonics. Science Podcast also conducts a telephone interview with Prof. Yu Siyuan (http://www.sciencemag.org/site/multimedia).


The integrated compact optical vortex beam emitters developed by Prof. Yu Siyuan’s team are only a few micrometers in size and thousands of times smaller than conventional elements. This breakthrough enables a large-scale and low-cost fabrication of silicon chips containing integrated optical vortex beam emitters, thus opening up new applications in optical communications, quantum information systems, sensing and etc.

Prof. Yu Siyuan is an internationally renowned expert in integrated photonics, chief scientist of a major EU project. Since 2011, he has established a high level research group at State Key Laboratory of Optoelectronic Materials and Technologies and School of Physics and Engineering, Sun Yat-sen University, and conducted world-leading research in semiconductor photonic element, integrated photonic technology and optical communications. This is the second time for Prof. Yu’s research to be reported on the cover of the journal Science. In 2008, he participated in the development of the world’s first integrated quantum photonic chip, which was featured on the cover of Science, and won the IET Innovation Awards.
