Watanabe Laboratory - Leading Material Science by Developing Ultra-High-Precision Measurement Technology for Terahertz Light

The Watanabe Laboratory at the Department of Physics, Faculty of Science and Technology, Keio University, conducts research and development aimed at understanding the microscopic properties of materials and creating new states of matter using light.

We are particularly focused on research using terahertz light.

Terahertz light, with a frequency 1/100 to 1/1000 lower than visible light, is gaining attention as a new light source. It possesses the crucial energy for investigating and manipulating new energy-scale phenomena in numerous materials that are still difficult to elucidate, ranging from quantum nanomaterials and superconducting materials to biomolecules.

At the Watanabe Laboratory, we are developing ultra-high-precision measurement technology for the amplitude, phase, polarization, and frequency information of terahertz light. By applying this technology to the observation and manipulation of materials, we hope to lead the next generation of material science.
