本研究利用田口实验优化法配合光束传播法设计优化光方向完全耦合器sin-square函数,能夠达到低串扰与短耦合器长度的目标,在田口实验优化法中我们选择直交表L9做为我们的实验平台。研究结果显示,使用BPM辅助设计方式配合田口方法可有效的減少设计优化光方向完全耦合器的实验数。在实验过程中我们尝试去找出并设定符合低串扰与短耦合器长度的绝热式光方向耦合器sin-square函数的结构参数范围,并且在田口实验优化法中的确认实验可以达到95%的信心指数。在这份研究中,我们证实利用田口实验优化法配合BPM辅助设计优化光方向完全耦合器sin-square函数是确实可行的。
In this study, Taguchi experiment optimization method with the beam propagation method to design and optimize the light direction perfect coupler sin-square function, to achieve the goal of low crosstalk and short coupler length, Taguchi Experimental Optimization method we choose orthogonal table L9 as our experiment platform. The results show that the use of BPM-assisted design with Taguchi method can effectively reduce the number of experiments designed to optimize the perfect coupler in the light direction. In the experiment, we try to find out and set the range of structural parameters of the adiabatic optical directional coupler sin-square function that meets the requirements of low crosstalk and short coupler length. And we can confirm the experiment in Taguchi experiment optimization method to reach 95% Confidence index. In this study, we demonstrate that it is feasible to use Taguchi’s experimental optimization method in conjunction with BPM-aided design to optimize the sin-square function of the light direction fully coupler.
