THz parametric sources and imaging applications

We are studying several novel steps toward real-life applications of terahertz waves, such as: i) palmtop terahertz-wave parametric generators; ii) printable terahertz sensors using metal mesh; iii) noninvasive detection of concealed drugs using terahertz wave scattering; iv) observation of MOSFET chips using an infrared laser THz emission microscope; and v) monolithic Fabry-Perot resonator for the measurement of optical constants in the terahertz range. In this paper, we introduce some of our recent activities.
