| Abstract: | The effect of the multimode inference (MMI) structure parameters,namely,the position and width of the input(output) waveguides,the width of the inference section,to the characteristics of the MMI splitter is considered.For given material parameters and width of inference section,a parameter space method is proposed to achieve a MMI splitter with good uniformity and low loss. |
