The terahertz region is one of the unexplored bands. This paper first reviews the present status of conventional high-speed devices, especially InP-based high electron mobility transistors (HEMTs), and addresses the technological problems facing the goal of terahertz operation. As an alternative approach to solve these problems, we developed a plasmon-resonant photomixer for realizing a coherent terahertz continuous-wave source. Preliminary results on electromagnetic response to impulsive photoexcitation at room temperature are reported briefly.
