提出了一种由TM-TE转换器和LiNbO 3偏振片组合而成的集成光、声可调谐波长滤波器。滤波器带宽为2.8nm，中心波长可通过调节驱动声频从λ = 1.45 pm调谐到λ = 1.57 pm。由于模式转换器中使用了组合的声/光带导结构，因此仅需要9 mW的极低声学驱动功率。
An integrated optical, acoustically tunable wavelength filter, consisting of a combination of TM-TE converter and integrated polarizer in LiNbO3, is demonstrated. The filter bandwidth is 2.8 nm; the center wavelength can be tuned from λ = 1.45 pm to λ = 1.57 pm by adjusting the driving acoustic frequency. Due to the combined acoustical/optical strip guide structure, used in the mode converter, a very low acoustic drive power of only 9 mW is required.
