Abstract

This article reports the variation of second-order harmonics (H2) with the DC bias voltage (DCBV) in surface acoustic wave resonators employing the SiO₂/LiNbO₃ structure. The H2 response depends on not only the amplitude but also the polarity of DCBV, and the dependence changes with the input frequency. On the other hand, linear and third-order nonlinear responses scarcely changed with DCBV. Possible origins of this phenomenon are also discussed.

温度补偿表面声波谐振器中二阶谐波对直流偏置电压依赖性的观察

本文报道了采用SiO2/LiNbO3结构的表面声波谐振器中二阶谐波H2随直流偏置电压的变化。H2响应不仅依赖于DCBV的振幅，而且还依赖于DCBV的极性，这种依赖关系随着输入频率的变化而变化。另一方面，线性和三阶非线性响应随DCBV变化不大。对这一现象的可能起源也进行了讨论。
