This presentation describes a high-sensitivity terahertz detection approach that utilizes photomixing to convert incoherent terahertz radiation to the radio frequency (RF) regime, at which high-performance RF electronics are available. We describe how utilizing plasmonic nanostructures provide a significantly enhanced wavelength conversion efficiency over a broad terahertz frequency range. Having a versatile design, this incoherent radiation detection scheme has broad applicability to quantum optics, chemical sensing, biological studies, medical diagnosis, high data-rate communication, as well as astronomy and atmospheric studies.
