q-plate for the Generation of Terahertz Cylindrical Vector Beams Fabricated by 3D Printing

We present the design, fabrication, and characterization of a q -plate with continuous birefringence variation at terahertz frequencies. This q -plate was fabricated by three-dimensional printing and is a simple solution for the generation of cylindrical vector beams. This device can find a number o...

Zusammenfassung:We present the design, fabrication, and characterization of a q -plate with continuous birefringence variation at terahertz frequencies. This q -plate was fabricated by three-dimensional printing and is a simple solution for the generation of cylindrical vector beams. This device can find a number of applications in future terahertz technologies such as telecommunications.
