摘　　要：本文用二维矢量时域有限差分 (FD- TD)法分析了平面光波导基模 (TE0 模 )和高阶模 (TE1 模 )的模场分布情况。分析基模时用了 5种不同形态的光源作为激励 ,所得的光场分布图在光场传播达到稳定后完全相同。所得 TE0 模和 TE1This paper analyzes the mode field distributions of TE 0 mode and TE 1 mode of plane wave guides by the two dimensional vector finite difference time domain (FD TD) method.Five kinds of optical sources are used as stimuli when analyzing TE 0 mode,and the final results of optical field distributions are the same after the standy spreading of optical waves.Furthermore,the two dimensional mode field distributions of TE 0 mode and TE 1 mode under stable state is identical to that discussed by the analytic methods.
