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: An electro-optic device having at least one liquid crystal cell for providing spatially variable control of light includes: a pair of opposed substrates sandwiching a liquid crystal layer therebetween; a pair of electrodes for applying an electric field therebetween, each electrode being deposited on a corresponding substrate; and a liquid crystal reservoir wall defining a lateral extent of the liquid crystal layer between the substrates. The reservoir wall includes: a first bottom barrier deposited on a bottom one of the pair of substrates; and a second curable top barrier deposited on the top substrate outside the first barrier. The first barrier and second uncured barrier are configured to merge on contact to retain liquid crystal material inside the reservoir wall prior to curing the second barrier. Also, a method of wafer level manufacturing and assembly of a liquid crystal optical device.
