摘要

A quasi-optical broadband terahertz detector using a zero bias Schottky diode mounted on a self-complimentary sinuous antenna has been developed. Design and characterization of this detector are described. Measurements show that a responsivity of 300-1000 V/W covering the frequency range of 150-440 GHz has been achieved. The detector performance has been compared to waveguide detectors covering four frequency bands up to 600 GHz. A recent measurement at 600-900 GHz yielded the same output voltage as a waveguide detector. The noise equivalent power level of this detector is estimated to be 5-20 pW / root Hz based on the measurements of similar detectors.
