Supported by of National 985 Project, the State Key Program of National Natural Science Foundation of China, Major Program of the National Natural Science Foundation of China and National High Technology Research and Development Program of China (863), optical fiber microstructure waveguide sensor and its signal demodulation method based on laser micro-machining platform have gained great achievements after years of efforts. High precision laser micro-machining platform has been built. In addition, laser writing methods, sensing mechanisms and big capacity networks of the optical fiber waveguide microstructure have also been studied. Almost 30 SCI papers cited (exclude self-citation) more than 400 times have been published in international top optical journals such as Optics Letters, Optics Express and so on. About 20 papers have also been accepted in the International Conference on Optical Fiber Sensors (OFS). The international optoelectronic industry well-known magazines: Photonics Spectra and Laser Focus World have made a special report on international influences of these achievements, and 2 invited papers have been published in the famous SCI journal Optical Fiber Technology. High temperature optical fiber microcavity sensor and system have been invented and developed. The core technology of the invention is international initiative, and has been successfully applied in some important national organizations. It is certificated as the high temperature parameter testing sensor with best comprehensive properties at present. Assessments from appraising meeting organized by the ministry of education are: "The results have reached the international advanced level, some indices have reached the international leading level”.
