Abstract | An increasing demand for fast and efficient random-access pointing has led to more investigation on beam steering approaches. This capability is crucial for LiDAR, remote sensing and many other emerging applications. Electro-Optical devices have advantages over mechanical approach that include a lower cost, faster steering rates, and a random-access beam pointing capability. We have designed, fabricated, Optimized, and characterized a recently proposed non-mechanical beam steering device based on the Pancharatnam-Berry phase. The architecture of our proposed device employs a linear array of phase control elements (PCEs) which are comprised of a fringe field switching electrode structure, are able to locally control the orientation of the liquid crystal director into a cycloidal pattern to deflect transmitted light. Efficiency data verifies a high beam steering efficiency for the proposed device. |
