<p>PROBLEM TO BE SOLVED: To provide an optical device that can be easily manufactured.SOLUTION: A variable liquid crystal device for controlling propagation of light passing through a liquid crystal layer uses a frequency-dependent material 1306 to dynamically reconfigure an effective electrode structure 1304 in the device. The frequency of a drive signal that generates an electric field in the device may be varied, and the frequency-dependent material has different charge mobilities for different frequencies. It is supposed that, at a low charge mobility, the frequency-dependent material has little effect on the existing electrode structures, and that, at a high charge mobility, the frequency-dependent material expands the fixed electrode 1304. The frequency-dependent material can be used to change the effective electrode structure and a spatial profile of the electric field, and further, changes optical properties of the liquid crystal, which allows the optical device to be frequency controllable.</p> |
