A new method for all optical space network based on fiber laser phase array technology

Abstract

A new method that adopt fiber laser phase array source to form all optics network in the deep space communication was proposed in this paper. The far-field light intensity figure of 1.55μm fiber laser phase array source was simulated, and the scanning range with changing among array components the phase was obtained. The number of array components was 3×3, wavelength was 1.55μm, and core radius was 10 μ m. The scanning range was ± 0.9909°when the distance of array components was 80μm. It was found that applying fiber laser phase array source can achieve scanning advantages with dynamic range in the all optics network.
