Paper Abstract

We describe a monolithically integrated THz transceiver consisting of a Schottky diode embedded into a THz quantum cascade laser (QCL) waveguide. Besides functioning as a heterodyne receiver for externally incident radiation, the device is a useful tool for characterizing the performance and dynamics of the QCL. Here we present an overview of the device, demonstrate receiver operation, and present laser dynamics measurements especially related to feedback of the QCL's emission due to retroreflections.
