摘要
利用强度—频率混合调制模型研究了基于色散器件的波束形成网络中色散导致的相位误差的变化规律 基于相位误差的分析,得到了0. 5ps延时精度下系统对最大色散值的限制,并指出存在最优的频率调制系数使系统色散容限最大;随着强度调制系数增大。
The variation rule of chromatic dispersion induced phase error of the beam former based on dispersion devices is studied using an intensity-frequency modulated model. Based on the phase error, the maximum dispersion limitation is presented when the phase precision is 0.5 ps. It is also shown that there exists an optimal frequency modulation index that makes the system dispersion tolerance maximum. When the intensity modulation index increases, the optimal frequency modulation index increases.
