本文介绍了一种基于平面电光热塑性棱镜和准直器透镜阵列的一维波控器件的设计和制作。由于取消了移动部件，所提出的装置能够克服现有扫描装置的机械限制，例如疲劳和低工作频率，同时保持较小的系统占地面积(∼0.5 mm×0.5 mm)。从实验数据来看，单级棱镜设计的最大偏转角为5.6°，级联三棱镜设计的最大偏转角为29.2°。透镜阵列显示了4μm的准直光束直径。
In this paper, we present the design and fabrication of a 1D beam steering device based on planar electro-optic thermal-plastic prisms and a collimator lens array. With the elimination of moving parts, the proposed device is able to overcome the mechanical limitations of present scanning devices, such as fatigue and low operating frequency, while maintaining a small system footprint (∼0.5mm×0.5mm). From experimental data, our prototype device is able to achieve a maximum deflection angle of 5.6° for a single stage prism design and 29.2° for a cascaded three prisms stage design. The lens array shows a 4μm collimated beam diameter.
