| 摘 要： | 提出了一种简单、高效的PZT压电陶瓷薄膜覆膜驱动的全光纤相位调制器数学模型,该模型计入了PZT压电陶瓷薄膜侧向压电常数d31对相位调制效率的影响,结果表明,对于PZT压电陶瓷薄膜覆膜驱动的全光纤相位调制器,这种影响是不能忽略的,由侧向压电常数d31引起的相位调制相当于由压电常数d33引起的相位调制的15%。应用此模型计算了PZT压电陶瓷薄膜、内电极以及外电极的机械与压电性能等参数对于全光纤相位器的相位调制效率的影响。该模型可应用于全光纤相位调制器的设计与优化。

| Abstract: | A theoretical model of all-fiber phase modulators with Lead Zirconate Titanate(PZT) coating was proposed by simply considering radial strain in all-fiber phase modulators.It has been shown that piezoelectric coefficient d31 of PZT is as important as d33 to allfiber phase modulatorsphase modulation of 15%.Effect of thickness and stiffness of the piezoelectric PZT films on the phase modulation efficiency is calculated.Results show that the materials properties of inner and outer electrodes of all-fiber phase modulators can be optimized with this model.This model is suitable for the design and optimization of all-fiber phase modulators. |

| Keywords: | all-fiber phase modulator frequency response PZT films |
