Smart liquid crystal beam deflector with laser ablated polymer micro grating structure

Boekbijdrage - Boekhoofdstuk Conferentiebijdrage

LC beam steering devices are realized using the combination of liquid crystal and polymer micro grating structures. The micro gratings are fabricated by combining two major techniques: laser ablation for a master mold and soft lithography for replicas with the desired optical materials. The LC components demonstrate effective beam deflections with a steering angle of 2.6° for both polarized monochromatic light(deflection efficiency >40%) and unpolarized white light beam (deflection efficiency >30%).
