【摘要】：光纤波片是光纤通信、光纤传感和全光信号处理系统的基本器件。光纤波片的性能取决于压电陶瓷的特性,而压电陶瓷的表现又由其驱动电路决定。为此,本文对压电陶瓷的驱动电路进行了深入研究,并制作了基于压电陶瓷的光纤波片,具体工作如下:(1)对压电陶瓷的特性以及典型驱动电路进行了分析;针对光纤波片可以实现各种偏振态变换的要求,设计了数字调压控制型与模拟调压控制型两种驱动电路。(2)根据原理图制作了驱动电路的样板,通过实验发现了设计中的问题,并进行了修改。测试了驱动电路的可行性,并比较了两种驱动电路的优缺点,最终选择了模拟调压控制型驱动电路作为实验电路。(3)设计并搭建了波片系统,测试了压电陶瓷驱动电路的性能。结果表明,设计制作的模拟调压控制型驱动电路,可以很好地驱动压电陶瓷,控制通过光纤中光的偏振态。
[Abstract]:Optical fiber wave-plate is the basic device of optical fiber communication, optical fiber sensing and all-optical signal processing system. The performance of optical fiber wave plate depends on the characteristics of piezoelectric ceramic, and the performance of piezoelectric ceramic is determined by its driving circuit. In this paper, the driving circuit of piezoelectric ceramics is deeply studied, and the optical fiber wave plate based on piezoelectric ceramics is made. The specific work is as follows: 1) the characteristics and typical driving circuits of piezoelectric ceramics are analyzed. Aiming at the requirement that optical fiber wave plate can realize all kinds of polarization state transformation, two kinds of driving circuits, digital voltage regulating control and analog voltage regulating control, are designed. According to the schematic diagram, the driving circuit template is made, and the problems in the design are found through experiments. The feasibility of the drive circuit is tested, and the advantages and disadvantages of the two drive circuits are compared. Finally, the analog voltage regulation control drive circuit is selected as the experimental circuit, and the wave-plate system is designed and built. The performance of the piezoelectric ceramic drive circuit is tested. The results show that the analog voltage control drive circuit can drive the piezoelectric ceramic well and control the polarization state of the light passing through the fiber.
