摘要
In this paper we describe the first experimental realization of the previously proposed optofluidic liquid crystal device based on electro-osmotic flows arising in the porous polymer (PET) film filled with a nematic liquid crystal (NLC). These flows induced Poiseuille's shear flow of NLC through the plane channels with a hometropic orientation, which resulted in the flow induced modulation of the intensity of light, passed through the channels. The additional application of magnetic field provided the stabilization of the homeotropic orientation. The results of numerical calculations of hydrodynamic and optical characteristics of the device were compared with the experimental data.
