With the rapid development and demand of all-optical integrated circuit, to assemble nanoscale light source with smaller scale and higher brightness has become a challenging task in today’s Nanophotonics field. At present, there are mainly two ways to assemble nanoscale light source. One is to use the light of semiconductor nanowires to make single semiconductor nanowires laser. The other is to use plasmonic technology to compress light in metal and semiconductor nanometer scale resonance to make nanoscale light source. However, the two methods cannot achieve higher brightness with the decreasing of device scale. Recently, Yang Guowei, professor of School of Physics and Engineering, SYSU, National Key Laboratories of Photoelectric Material and Technology and Nano Technology Center and his research group, associate professor Dong Jianwen and Professor Li Baojun have made significant progress in the assembling of nanoscale light source. The relevant results were published in the front cover of the latest international material science journal Advanced Materials (Adv. Mater. 23 (26) (2011) 2937-2940).
