We fabricate wave plates for terahertz waves using a 3D printer. The wave plates base on the physical mechanism of form birefringence. Applying mechanical pressure to the plates allows for continuously tuning of the optical retardance.
We present a terahertz radiation detector that measures both transverse components of a terahertz single cyclepsilas electric field, allowing the study of polarization dependent properties of materials. Measurements of birefringence in quartz are presented.
