The relation between coupling ratio of 1 × 7 tapered mixing-rod POF couplers and the length of tapered rod waveguides through numerical simulation by ray tracing method is given.

利用光线追迹法进行数值仿真得到了锥形混合棒塑料光纤耦合器的分光比与其长度的关系。

The simulated results show that the coupling ratio oscillates around the uniform splitting point of 0.143 with the tapered rod waveguide length increasing.

数值仿真表明：这种耦合器的分光比随锥形光波导长度增加，在0.143（即均分处）上下呈振荡型变化。
