    摘要: Variable liquid crystal devices for controlling the propagation of light through a liquid crystal layer use a frequency dependent material to dynamically reconfigure effective electrode structures in the device. The frequency of a drive signal that generates an electric field in the device can be varied, and the frequency dependent material has different charge mobilities for the different frequencies. At a low charge mobility, the frequency dependent material has little effect on the existing electrode structures. However, at a high charge mobility, the frequency dependent material appears as an extension of the fixed electrodes, and can be used to change the effective electrode structure and, thereby, the spatial profile of the electric field. This, in turn, changes the optical properties of the liquid crystal, thus allowing the optical device to be frequency controllable.

    摘要: Methods and apparatus for testing operation of a single or multiple tunable active optical device(s) operated by one or more driving electrodes are described. Test methods and apparatus are provided for device testing without necessarily requiring direct physical contact with the driving electrodes. Testing subjects devices to incident light along an optical path and to an external electric field applied to the device producing a dipolar charge distribution within the electrodes, causing the device to operate. The effect of device operation on incident light is optically sensed. The sensed effect is analyzed to identify device defects. Test methods and apparatus are provided for testing multiple unsingulated devices during fabrication employing a strip contact structure having contact strips connected to multiple devices and extending to wafer edges, such that singulating devices leaves portions of the strip contact structure exposed on device dice edges providing electrical contacts in use.

    摘要: A liquid crystal optical device is described configured to provide variable beam steering or refractive Fresnel lens control over light passing through an aperture of the device. The device includes at least one layer of liquid crystal material contained by substrates having alignment layers. An arrangement of electrodes is configured to provide a spatially varying electric field distribution within a number of zones within the liquid crystal layer. The liquid crystal optical device is structured to provide a spatial variation in optical phase delay with a transition at a boundary between zones which is an approximation of a sawtooth waveform across the boundaries of multiple zones. The arrangement of electrodes, device layered geometry and methods of driving the electrodes increase the effective aperture of the overall optical device.

    摘要: An electrode structure is proposed for controlling a spatially non-uniform electric field driving a tunable liquid crystal lens or beam steering device. The spatially non-uniform electrode structure enables the generation of a predetermined spatially non-uniform electric field profile where complex capacitive coupling between multiple different electrically floating neighboring electrode segments is employed for the generation of the electrical field of desired form by supplying an initial electric potential to a limited number of electrodes.
