Paper Abstract

A high efficiency, low cost, low voltage operation liquid crystal on silicon beam steering device with multiple angles addressing capability is developed. Currently, seven steering angles with as high as 92.7% efficiency are achieved within 2.85 v. The device's design consideration, fabrication process as well as the characterization results are described.
