In this study, we demonstrate a method to generate circularly polarized terahertz radiation using a monolithic superconducting device. a square-shaped Bi-2212 single crystal mesa with trimmed edges is used to control the emission polarization with the applied bias voltage. These results will be useful for future compact wireless devices and spectroscopy systems.
