    Abstract: 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.

    Abstract: A wafer level method of manufacturing a liquid crystal optical device removes the need for a rigid barrier fillet while minimizing any risk of contamination of the liquid crystal. An uncured adhesive may be deposited on a bottom substrate and partially cured to form a liquid crystal barrier. After addition of the liquid crystal and a top substrate, the adhesive is fully cured to bond the substrate layers together. An uncured adhesive may be used together with the partially cured adhesive, and may be deposited separately or filled into an extracellular matrix surrounding a plurality of liquid crystal cells. The adhesive may be cured by a variety of means, including light that may be spatially modulated. One or both of the substrates may be deformed during assembly so as to create a structure with a lensing effect on light passing through the liquid crystal region.

    Abstract: A controllable light propagation system includes a light guide elongated in a first direction, a controllable liquid crystal (LC) element including an LC material and having a first side adjacent the light guide to define a dynamic interface between the light guide and controllable LC element, and an array of electrodes arranged at different locations along the first direction. The array of electrodes arranged along the first direction are selectively activatable to generate electric fields in the LC material to control a transmissivity of the dynamic interface between the light guide and the controllable LC element, thereby allowing a controlled extraction of light at selected locations along the light guide. An array of optical elements may be provided at a second side of the controllable LC element to deflect or otherwise influence the extracted light, e.g., as a function of the location of the extracted light along the first direction.

    Abstract: A reprogrammable intraocular adaptive lens prosthesis apparatus is provided. The apparatus includes a tunable liquid crystal lens (TLCL) encapsulated in the intraocular prosthesis with control electronics and a power source or in the intraocular prosthesis with a control signal receiver while an external control electronics package transmits the control signal. The TLCL is driven in response to a stimulus signal to provide accommodation. The TLCL corrects other visual shortcomings of the natural eye. The intraocular prosthesis has a remote programmable TLCL controller configured to recalibrate the TLCL to compensate for dynamic adaptation of the eye over time.
