Abstract : Photoconductive switches are widely used for emission and/or detection of terahertz pulses. The emitted polarization is fixed by the design of the electrodes. In this work, innovative designs of photoconductive switches are proposed providing full electrical control on the direction of polarization of the emitted field and its detection. These designs are based on monolithic on-chip solution with an interdigitated scalable geometry. It allows fast polarization modulation ability without the need of external mechanical components, and polarimetry measurements with a large area receiver. It opens the fields of precision terahertz polarimetry.
