The generation of efficient, tunable, coherent, and circularly polarized continuous wave terahertz radiation would have far reaching implications in wireless communications, imaging, and spectroscopy. In this study, we experimentally demonstrate a method to generate a polarized terahertz emission directly from a mesa-shaped superconducting Bi-2212, monolithically without using any external optical devices.These findings pave the way for further Bi-2212 based THz polarization control sources, antennas, and arrays.
