Abstract
The generation of a wide-range THz wave is investigated from a photoconductive antenna excited using
a chaotic oscillation multimode semiconductor laser with optical delayed feedback by an external mirror.
We compared the properties of the generated THz wave using laser chaos with those using a CW steady
state laser which excited photoconductive antenna. Using a laser chaos, a stable THz wave was obtained.
For a high sensitive detection, a metal V-grooved waveguide (MVG) is also used. The 1.6 times la
