Abstract :
We have developed compact THz-wave parametric generators with different characteristics that operate at room temperature. One generates high energy and broadband THz waves, being suitable for detecting the transmission of absorptive or diffusive samples, and the other has a potential of wide tunability and narrow linewidth, useful for spectroscopic measurements. Also, we are studying several novel steps toward real-life applications of terahertz waves, such as, noninvasive detection of concealed drugs, observation of MOSFET chips using an laser THz emission microscope, printable terahertz sensors using metal mesh. In this paper, we introduce some of our recent activities.
