Performance of a compact, continuous-wave terahertz based on a quantum-cascade laser [PDF]

, 2010
We report on the development of a compact, easy-to-use terahertz radiation source, which combines a quantum cascade laser (QCL) with a compact, low-input-power Stirling ...

Terahertz Digital Holographic Imaging of Voids Within Visibly Opaque Dielectrics

, 2014
Terahertz digital off-axis holography (THzDH) has been demonstrated as a non-destructive tool for imaging voids within visually opaque dielectrics. Using a raster scanning heterodyne detector, the imager captures lensless transmission holograms formed by

Research on Direct Detection Method and Performance of Single-photon Counting Terahertz Radar

Leida xuebao
The conventional terahertz radar suffers from limited operation range for long-distance, noncooperative target detection due to the low transmitter power and atmospheric attenuation effect, both of which pose a hindrance in meeting the requirements of ...

Planar terahertz metamaterials for strain sensing

, 2012
Extent: 2p.We present two designs of planar terahertz metamaterials for strain sensing. A series of resonance frequency shifts are obtained with differing gap widths when the sensor is under mechanical compression.

Room temperature GaN/AlGaN self-mixing terahertz detector enhanced by resonant antennas

, 2011
This letter focuses on the fabrication and characterization of a terahertz detector integrated with a group of low pass filters and resonant antennas. The detector operates as a self-mixer on GaN/AlGaN high electron mobility transistor(HEMT).
