Research Abstract |
The study on optical extraction technique of terahertz-wave carrier by using a pair of semiconductor lasers and photoconductive devices for near-infrared light was carried out. The expected characteristics were predicted on the basis of the experiment carried out at 92 GHz. Homodyne and self-heterodyne configurations were implemented to detect faint terahertz signals around 340 GHz. Although the desired signal was not detected, it might become possible to detect it by further improving the conversion losses as well as radiation impedance-matching conditions.
