Device and method for improving properties of ferroelectric liquid optical switch

The invention discloses a device and method for improving the properties of a ferroelectric liquid optical switch. The device comprises a container body which is made of an insulating material, two electrodes are arranged on the two corresponding side faces of the container body, the electrodes are the upper electrode and the lower electrode respectively, the upper electrode and the lower electrode are provided with protruding electrodes respectively, the protruding electrodes are located between the upper electrode and the lower electrode, and the ferroelectricity is introduced into the container. By introducing the protruding electrodes between plate electrodes, since the protruding electrodes have a small curvature radius, when voltage with the same amplitude is applied to plates, highelectric field intensity and electric field gradient can be obtained, the response variable of the optical switch is increased, and finally, the properties of the ferroelectric liquid optical switch can be improved. 本发明公开了种提高
