Abstract :
Generation of a wide-range and stable THz waves from a photoconductive antenna excited by a multimode semiconductor chaotic oscillation laser with an optical delayed feedback using an external mirror is investigated. A high bias voltage is also used to generate wide range THz wave. The THz wave near to 1 THz is obtained using this system.
