摘　　要：用COMSOL对十九芯光纤的各个模场进行仿真,发现同相位超模的远场呈现准高斯分布,其发散角最小,具有最好的光束质量。并通过分析各个模式的光束质量因子M2和桶中功率PIB两个参数,再次证明十九芯光纤的同相位模式具有最好的光束质量。The mode field distributions of 19-core optical fiber are simulated by using COMSOL software. It isfound that far field with in-phase mode presents quasi-Gauss distribution, which has small divergence angle and thebest beam quality. In-phase mode with the best beam quality is proved through analyzing beam quality factor M2 and power-in-bucket（PIB）.
