In this paper, an optofluidic phase modulator array based on the piezoelectric effect is designed, fabricated, and characterized. This array is composed of three piezoelectric ceramics arranged on the vertices of an equilateral triangle. A transparent liquid fills the inner cavity of the ceramics. Due to the inverse piezoelectric effect, the length of the transparent liquid is changed at different voltages, which contributes to the optical phase modulation. According to experiment results, it is found that our modulator arrays exert continuous optical phase adjustment ability. When the voltage ranges from 0 to 135 V, the relative length variation reaches up to 9.286 µm, and consequently our proposed modulator arrays perform about 9.685 π optical phase modulation.
本文设计、制作并表征了一种基于压电效应的光流控相位调制器阵列。该阵列由三个排列在等边三角形顶点的压电陶瓷组成。透明液体填充在陶瓷的内腔中。由于逆压电效应，透明液体的长度在不同电压下会发生变化，这有助于实现光相位调制。根据实验结果，发现我们的调制器阵列具有连续的光相位调节能力。当电压在0至135 V范围内时，相对长度变化高达9.286 µm，因此我们提出的调制器阵列可实现约9.685 π的光相位调制。
