Terahertz Cylindrical Lenses Based on Three-Dimensional Printing Technique
摘要
设计了一种工作在太赫兹波段的柱透镜,并且使用三维(3D)打印技术制作出了样品。对样品进行了测试,将测试结果与数值仿真结果以及商用太赫兹柱透镜的测试结果进行了对比。结果表明,两种柱透镜的焦距均在100 mm左右,与仿真结果相符,且打印的柱透镜在不同传播距离下的光斑半峰全宽与商用柱透镜的很接近,证明了3D打印技术可以用于制作太赫兹波段的柱透镜等光学器件。
Abstract
A cylindrical lens working in the terahertz (THz) frequency range is designed and its sample is also fabricated by using the three-dimensional (3D) printing technique. A test on this sample is conducted. The comparison among the testing results, the simulation results, and the testing results of the commercial THz lenses is made. The results show that the focal lengths of two kinds of lenses are both about 100 mm, which matches with the simulation results. Moreover, under different propagation distances, the full widths at half maximum of spots for the printed lenses are very close to those for the commercial lenses, which proves that the 3D printing technique can be used in the fabrication of THz optical devices, such as cylindrical lenses.
