The College of Physics and Optoelectronics Engineering was developed from the physics professors of the PLA Military Engineering College (Harbin Military Industry), which was established in 1953. The college has a “Optical Engineering” postdoctoral research mobile station, “Optical Engineering” doctoral program. It has advanced research platforms such as the Key Laboratory of “Fiber Integrated Optics” of the Ministry of Education, the Key Laboratory of “Marine Photonic Materials and Device Physics” of the Ministry of Industry and Information Technology, the Innovation and Intelligence base of the Ministry of Education of “Micro-structure Functional Fiber for Engineering Applications” and the Key Laboratory of “Fiber Sensing Science and Technology” of Heilongjiang Province.
At present, the Key Laboratory of “Fiber Integrated Optics” of the Ministry of Education has formed a multidisciplinary research team consisting of optics, physics, electronics, materials, biology, machinery and other disciplines, including 1 national candidate, 1 Outstanding Young Persons, 2 national young talents, 2 New century talents of the Ministry of Education, 2 Outstanding Young Persons of Heilongjiang Province, and 2 Longjiang scholars. In the past five years, the school has undertaken more than 110 national, provincial and ministerial projects such as key projects of the National Natural Science Foundation of China, National major instrument development projects of the Ministry of Science and Technology, and major international cooperation projects of the Ministry of Science and Technology (including 49 projects of the National Natural Science Foundation of China), with a total fund of more than 99 million yuan. He has won 6 provincial and ministerial awards, including 1 second prize of technological invention of the Ministry of Education, 1 first prize of provincial technological progress, 1 first prize of provincial natural science and 4 second prizes; He published 627 high-level papers indexed by SCI, and granted 256 invention patents.
