Abstract

Based on diffraction theory, the performance of space optical communication systems consisting of a transmitting antenna, receiving antenna, and fiber coupling system is analyzed in detail. Besides, several practical situations are also involved such as antenna defocus and fiber deviation. According to the simulation results, defocusing on the primary mirror will improve the transmission efficiency and coupling efficiency of the system in some cases. Coupling efficiency can be increased by 15.57%; when the primary mirror of the antenna is defocused, the coupling efficiency can be increased by 15.31% by adjusting the position of the optical fiber..
