摘要: 本文提出一种稳定的模拟光波导中波传播的显式时域方法,该方法以Dufort-Frankel法和变量代换法为基础,采用了显式的差分方法,计算快速,节省内存,行之有效;应用该方法在光波导中将500fs的光脉冲传播2mm,得出了光脉冲的瞬态值及波导参数对脉冲的影响情况。Abstract: An explicit and stable time-domain method for solving the propagation of wave envelope in optical structures is proposed. Based on Dufort-Frankel method and variable change, it is a explicit difference. The method takes less memory and less time and it is applied to propagation of a 500 fs pulse in a waveguide over 2mm. Transient behavior of the pulse and the effects of the waveguide parameters are given.
