摘要
标量三维交替方向隐式FD-BPM是分析波导器件的有效方法,利用这种方法分析多模波导器件的模传播常数及模场分布.以Ti:LiNbO3多模波导作为算例,给出此方法的公式体系以及计算结果.
The 3-Dimension scalar alternating direction implicit finite difference beam propagation method (ADI FD-BPM) is an effective simulating tool for the 3-D waveguide. This method is used to get the mode constants and mode fields of multi mode waveguide devices. The example of a Ti. LiNbO3 multi mode waveguide is given; and the mode fields of three modes are got.
