Effect of metal V-grooved wave guide gap width on high efficient CW-THz TDS systems

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. 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. As the MVG gap is narrower from 200 to 20[μm], the detected signal is increased about twice.
