Abstract

We present a device concept for scanning large (>1 cm) laser beams using a domain microengineered ferroelectric device. In our design, the large input beam is divided into smaller beamlets, which are then individually deflected through an angle, and then recombined in the far-field to reconstruct the large beam. As a demonstration of this concept, a five-stage cascaded rectangular domain micropatterned scanner device with 13 beamlet channels was fabricated in LiTaO 3 and was demonstrated to deflect a 1.064 μm infrared laser beam by a total of 10.3° at 5.39 kV/mm.
