Information Photonics Research Department

The Information Photonics Research Department is an important part of the national key laboratory of transient optics and photon technology, mainly in research of many fields such as optical fiber and integrated optics, micro-optics, biology optics, optical fiber optical component, photoelectric functional material and information optics, etc, and has trained many professional talents in many fields for China.
The Research Department plans 30 permanent researchers, but currently boasts 21 permanent researchers, including four research fellows and three associate research fellows and senior engineers, of whom there are three doctor tutors, two post-doctorates and three doctors. The Department now has two post-doctorates for research, two doctors under their program and three postgraduates for Master. The researchers have average age under 35, and are characterized by high educational degree, young age but insufficient team members. 
Over the past five years the Department has undertaken and completed multiple national projects, including 12 CAS “100 Talents Program” projects, five “863 Program” projects, one national innovative pre-research project, two key projects under support of national fund for natural science, five provincial-fund projects and six cooperative research and development projects with local government and companies. In addition, we also attach importance to development of civil products, and has researched and developed more than 10 projects in special optical fiber, optical fiber sensing and special glass, etc, of which GF-86 silver-coated glass powder has been put into batch production, with good social benefit gained. 
The Department boasts many types of equipment for optics material thermal properties, optical parameter measurement instrument, prefabricated optical fiber rod manufacturing equipment and optical fiber scale production equipment. All the instruments are open to the outside departments and for cooperative research.
We welcome people with high ideals in China’s optical fiber and integrated optics, micro-optics and biology photonics to join our department. 

In 2008 the project of “Gradient Refraction Index Optical Material and Micro-lens Series” was granted National Award for Scientific and Technological Progress Class II.
