论文摘要
我们提出了一种机械流动力学实验设置，其中微流体运动操纵了悬浮的氧化石墨烯氧化石墨烯液体晶体的光学双折射。通过在微通道中流动的氧化石墨烯液晶来改变样品的双折射。通过以五个流速测量普通和非凡的折射率，可以确定样品的双折射的值。我们的结果表明，通过调整石墨烯氧化石墨烯纳米薄片的浓度和流量，可以控制诱导的双折射。还表明该方法可以用作光学开关。
We propose a mechanical-hydrodynamical experimental setup in which the microfluidic motion manipulates the optical birefringence of levitated graphene oxide liquid crystal. The birefringence of the sample is changed by flowing graphene oxide liquid crystal in the micro-channel. By measuring the ordinary and extraordinary refractive indices at five flow rates, one can determine the value of the birefringence of the samples, precisely. Our results demonstrate that, by adjusting the concentration and flow rate of dispersion of the graphene oxide nano flakes, the induced birefringence can be controlled. It is also shown that this approach can be used as an optical switch.
