On March 20, 2020, Chinese Laser Press, a press hosted by Shanghai Institute of Optics and Fine Mechanics, Chinese Academy of Sciences (SIOM, CAS), and the Chinese Optical Society, released the 2019 Award for China’s Top 10 Optical Breakthroughs. 20 research results, classified by fundamental research and applied research, were awarded, among which some hot topics, such as photonic chip, smart laser and full color laser display were applauded by the awarding committee.

Initiated by Chinese Laser Press in 2005, this awarding event aims to disseminate innovative and important achievements by Chinese researchers and further boost the development of optics in China.

The topics of this award cover all fields related to optics. The whole evaluation process consists of three stages, i.e. recommendation, preliminary selection and final selection.
