Abstract

Generation of a wide-range THz wave from a photoconductive antenna excited by a multimode semiconductor chaotic oscillation laser with an optical delayed feedback using an external mirror is investigated. An optical fiber is also used for easy alignment. The properties of the generated THz wave are compared with those of generated THz wave by using a CW steady state laser.
