摘　　要：提出采用光纤激光相控阵光源在深空通信中组成全光组网的新方法,模拟了1.55μm的光纤激光相控阵光源在深空通信中的远场相对光强图,得到了通过改变阵元之间的相位控制扫描角度,阵元数目为2×2,波长为1.55μm,纤芯半径为10μm,阵元在间距80μm时,扫描角度为±0.990 9°,发现了利用光纤激光相控阵光源在深空全光组网高速通信中具有动态角度可扫描优势。A new method of all-optical networking using fiber laser phased-array sources in deep space communication is proposed. The far-field relative intensity chart of 1.55μm fiber laser phased-array sources in deep space communication is simulated. The scanning angle is controlled through adjusting the phases between array elements and the scanning angle is ± 0.990 9° when the wavelength, core radius, array elements number and spacing are 1.55μm, 10μm, 2 × 2, 80μm respectively. Simulation results show that the fiber laser phased-array sources have advantage of dynamic angle scanning in high speed communication for deep space all-optical networking.
