摘要

提出了基于多模干涉(MMI)结构的1.3和1.55 μ m工作光滤光片的优化设计。通过在输入/输出波导交界处采用锥形结构，可以提高消光比和插入损耗。在确定性能因子的基础上，通过模态传播分析确定了MMI的最优宽度和长度，通过光束传播法确定了最优锥度宽度。

Multimode interference optical filter for 1.3 and 1.55 μm by using taper structures

Optimal design of optical filter for 1.3 and 1.55 mum operation based on multimode interference (MMI) structure is presented in this paper. By using taper structure at the junction between input/output waveguides, the extinction ratio (ER) and the insertion loss (IL) can be improved. Based on the defined performance factor, the optimal width and length of MMI is determined by using a modal propagation analysis and the optimal taper width is determined by performing beam propagation method.
