摘要/Abstract

摘要： 为了研究基于光子灯笼的模式分集接收系统在星地链路中对大气湍流的补偿作用。采用平行光管模拟星地下行链路的平行光,使用30cm口径的接收望远镜进行了演示验证实验。实验结果表明,采用光子灯笼的接收系统的基模比单模光纤的接收功率大4dB左右,而光子灯笼的3个模式总接收功率比单模光纤的接收功率大5dB左右。采用光子灯笼接收之后,中断概率下降39%以上。

Abstract: In order to study the compensation effect of mode diversity receiving system based on photonic lanterns in satellite ground link under atmospheric turbulence a parallel light tube is used to simulate the parallel light of the underground link of the satellite, and the demonstration and verification experiments are carried out by using a 30cm receiving telescope. The experimental results show that the receiving power of fundamental mode that uses the photonic lantern is about 4dB higher than that of the single-mode fiber, and the total receiving power of three modes of photonic lanterns is about 5dB higher than that of the single-mode fiber. After receiving with photonic lanterns, the interruption probability decreases by more than 39%.

Key words: satellite to ground optical communication, atmospheric turbulence compensation, mode diversity, photonic lantern, coupling efficiency
