将声流混合与光流集成相结合，我们已经展示了一种由声激励振荡微泡驱动的单层平面光流开关。该器件的开关速度为5 Hz，插入损耗为6.02 dB，消光比为28.48 dB。凭借其简单性，低流体消耗以及与其他微流体设备的兼容性，我们的设计可以为许多芯片实验室应用提供一系列廉价但有效的光学开关。(C)2012年美国物理学会。[http：//dx.doi.org/10.1063/1.4742864]
Merging acoustofluidic mixing with optofluidic integration, we have demonstrated a single-layer, planar, optofluidic switch that is driven by acoustically excited oscillating microbubbles. The device was found to have a switching speed of 5 Hz, an insertion loss of 6.02 dB, and an extinction ratio of 28.48 dB. With its simplicity, low fluid consumption, and compatibility with other microfluidic devices, our design could lead to a line of inexpensive, yet effective optical switches for many lab-on-a-chip applications.
