[China Instrument Network Instrument Development] "1 foot square, weighing about 5 kg, measuring indicators have reached the international advanced level, research and development costs less than half of foreign." Recently, Nanjing University of Aeronautics and Astronautics researched a girl Heng Yuqing successfully developed a low-cost, high-performance general-purpose optical component analyzer.

This analyzer successfully integrates the spectrum response test link of the photodetector and the electro-optic modulator in one system. In the same instrument, it can measure the spectrum response of electro-optical and optical-electric devices. At present, China Southern Airlines Microwave Photonics Laboratory led by its advisor, Professor Pan Shilong, and the giants of the global instrument industry, Rode and Schwarz, have already achieved cooperation. After subsequent iterations of the General Optical Component Analyzer, they will be supported by Rohde & Schwarz. Watts Corporation's vector network analyzer, the two sides jointly promote the application.
Talking about his “great invention,†Heng Yuqing said: “As a sophomore, Pan taught us a professional course in “Electromagnetic Field and Microwave Technology.†His knowledge, humour, and kindness made me enjoy it all at once. The course also has an interest in photoelectric research.†The understanding of life, let Heng Yuqing’s understanding of the photodetector, is no longer abstract and interesting. As her research progressed, she became increasingly aware of the magic of photodetectors, and her interest in research on this subject has grown dramatically.
“Since there is a conversion device from an optical signal to a microwave signal, what device can achieve electricity-to-light conversion?†After the second half of 2016, after obtaining the qualifications for insurance research, Heng Yuqing learned the wisdom of Professor Pan Shilong. Into the microwave photonics laboratory, to explore the magic of the "electrooptic modulator".
For the measurement of the frequency response of photodetectors and electro-optic modulators, Heng Yu has applied for two invention patents. It is reported that General Optical Component Analyzer has been applied in the Institute of Semiconductors of the Chinese Academy of Sciences, Southeast University, 8 CLP, 44 Zhongdian, Beijing Zhongxing and Suzhou Laxense. "We will continue to improve the instrument based on feedback from use." , Heng Yuqing introduced.
This universal optical component analyzer with its own independent intellectual property rights is expected to break the long-term foreign companies almost monopolize the market situation of optical-electrical and electro-optical measuring instruments, effectively supporting China's high-speed electro-optic modulators and high-speed photoelectric detectors. The development, detection and application of optical components such as core photonic integrated chips have helped boost the upgrading of China's information industry.
