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 1.6times larger amplitude of signal is detected using MVG compared with that using conventional Si lens system. And this system applied to THz time domain spectroscopy. |
