Patent number: 9874774Abstract: 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.Type: GrantFiled: August 4, 2015Date of Patent: January 23, 2018Assignee: LENSVECTOR INC.Inventors: Bahram Afshari, Karen Asatryan, Peter P Clark, Tigran Galstian, Michael J.
