Now 2 big projects are running !

Grants-in-Aid for Scientific Research (KAKENHI) (S) "New development of nonlinear photoelectronics based on terahertz strong field physics" 17H06124

  • Research project about interaction between strong terahertz field and solid materials. This is a collaborative research project with Prof. Yanagi at Tokyo Metropolitan University and Prof. Katayama at Yokohama National University.

JST-ACCEL "Terahertz optical science and technology in semiconductors"

For international students

We welcome you to join us to study terahertz optical science for your PhD or research project. Please contact Prof. Dr. Koichiro Tanaka (kochan[at]scphys.kyoto-u.ac.jp) or Associate Prof. Dr. Nobuko Naka (naka[at]scphys.kyoto-u.ac.jp) for further details.
