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 1.55 μm 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 1.55 μm, 10 μm, 2×2, 80 μm 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.
