Abstract
Generation of a wide-range THz waves are investigated from a photoconductive antenna excited using a chaotic oscillation multimode semiconductor laser with optical delayed feedback by an external mirror. The properties of the generated THz wave are compared with those of a case excited by a CW steady state laser. The stable THz wave is obtained from the multimode-laser diode excited photoconductive antenna by using a laser chaos. For a high sensitive detection, a metal V-grooved waveguide (MVG) is also used. The 1.6 times signal is detected using MVG compared with conventional system using Si lens.
