摘要
利用微流道内不互溶液体界面可以形成平面波导结构。通过调节不同液体的相对流速控制光线的出射方向实现光开关的功能,仿真研究了一种1×2微流控光开关的特性。当保持芯包层相对流速v=3.8、芯层相对宽度d=0.66时,光从下端口出射;当芯包层的相对速度v=4.3、芯层相对宽度d=0.76时,光从上端口出射。
The planar waveguide can be formed by incompatible interface in the micro channel. By controlling the velocity of two different fluids, it change the direction of the emergent light and realize the function of optical switch. A 1 ×2 micro fluidic optical switch is simulated and its property is investigated. The light exits from one outlet when the relative velocity reach at 3.8 and the relative width of core fluidic is 0.66. The light exits from the other outlet while the relative velocity reach at 4.3 and the relative width of core fluidic is 0.76.
