On behalf of the Program Committee, we are pleased to announce that the 8th International Symposium on Ultrafast Phenomena and Terahertz Waves (ISUPTW 2016) will be held in Chongqing, China from October 10 to 12, 2016. ISUPTW 2016 is organized by Chongqing Institute of Green and Intelligent Technology (CIGIT), Institute of Physics (IP), CAS, the Institute of Optics, University of Rochester, the Capital Normal University (CNU), the University of Shanghai for Science and Technology (USST), and the Optical Society of America (OSA).

ISUPTW, an international symposium, is devoted to strengthening the collaboration among worldwide researchers and promoting the development in Ultrafast and Terahertz science and technology. The biennial symposium, initiated in 2002, has been held in Beijing, Shanghai, Nanjing, Tianjin, Xi'an, and Wuhan. It brings together scientists, technologists, and students from more than 10 countries and typically hosts 150-300 participants.

This symposium provides an excellent opportunity to share and exchange ideas. We look forward to welcoming our friends and colleagues from all around the world. The paper submission system is open now. We warmly invite you and your colleagues as well as students to submit the latest work. The contributed papers will be archived on EI Compendex by OSA. We believe you will not only enjoy the exchange and discussions on ultrafast phenomena and terahertz wave, but will also have a memorable experience in Chongqing, China.

It is our great pleasure to inviteyou to attend this symposium.Your contributions are crucial to the success of these exciting events.
