中文摘要：
设计了一种基于多模干涉（MMI）波导结构的可调谐功率分配器，利用高分子含氟聚酰亚氨材料的热光效应，调节多模波导中局部区域的折射率，可实现两单模输出导模的输出功率比在较大范围内连续可调谐。BPM防真证实了这一结果。
英文摘要：
By using the thermo-optieal effect of fluorinated polyimide to modulate the index in partial region of multimode waveguide, a tunable polyimide-based multimode interference （MMI） waveguide power splitter is designed. The characteristics of power splitter are simulated by the finite-difference beam propagation method （BPM）,and the results show that large tuning range can be realized.
