Abstract-Applications


  • Jiandong Sun
Nonresonant self-mixing terahertz detectors have a few advantages concerning the room-temperature operation, high sensitivity, wide response spectrum, high speed, and high signal-to-noise ratio over other slow bolometric detectors for room-temperature applications. Terahertz imaging based on single-pixel detectors and a 1×9 linear detector array are demonstrated with a high spatial resolution and a high signal-to-noise ratio. The single-pixel detector is successfully implemented in a Fourier transform spectrometer and a fast Fourier transform spectroscopy of a 900 GHz terahertz signal is demonstrated. Although the demonstrated self-mixing detectors are far from optimal in sensitivity, speed, stability, and reproducibility, this technology has a great potential to be further developed and optimized to bring many terahertz applications at room temperature into reality.
