Abstract
A multiple-angle liquid crystal blazed grating beam deflector has been developed. It consists of a stack of liquid crystal blazed gratings where each layer can deflect incident light with very high efficiency into one of two different directions depending on the driving condition. Four steering angles (10.8 degrees, 7.2 degrees, 3.6 degrees, 0 degrees) with about 70% diffraction efficiency are demonstrated with 15 V. The device's working principle, design considerations, fabrication process, and characterization results are described.
