Advanced Terahertz Spectroscopy with High-power Terahertz Light Source and its Application to Materials Science

Research Project Outline

We will develop a tunable high-power terahertz light source whose peak electric field is comparable to that inside the active semiconductor device and try to establish a novel non-linear terahertz spectroscopy for solid, liquid, and biological materials. We will visualize terahertz coherent transients in mesoscopic structures with real-time near-field terahertz microscope and semiconductor quantum structures using high-power terahertz light source. These advanced terahertz technologies will open new aspects in solid state physics such as nonperturbative nonlinear optical processes.
