Research on Designing Approaches for Device and Integration of Photonic Integrated Interferometric Detecting System
Based on the wave effect of light wave, the optical path matching waveguides, array waveguide gratings, phase modulators and multimode interference couplers are designed by using the beam propagation method. On this basis, the coupling characteristics of the photonic integrated device are analyzed and calculated, and a complete photonic integrated chip is designed. Through the analysis, research and optimization of each module of the photonic integrated interferometry system, an electronic prototype of the photonic integrated interferometry detection system is designed. The results show that the minimum loss of the designed photonic integrated device is 0.07 dB, and the loss of the photonic integrated chip is 7.46 dB. When the equivalent aperture is 110 mm and the system height aperture ratio is 1∶4, the electronic prototype of the photonic integrated interference detection system has the technical indexes of 0.5 ° field of view and 5 m spatial resolution at 100 km.
