I study optical properties in semiconductors and organic materials by means of time-resolved and/or nonlinear spectroscopy with ultrafast optical pulses. Recently I mainly study optical properties of semiconductor nanostructures. For a carrier in education, I have been teaching lectures concerning optics and optical physics for more than ten years, such as “Electromagnetics II”, “Optical physics”, “Quantum optics”, and “Optical properties in solids”. Also I have been teaching a general educational lecture named “Physics in daily life” for more than ten years.
(Subject of research) Ultrafast Optical Signal Processing Excitonic Nonlinear Optics Optical properties of inorganic-organic materials Optical properties of Photocatalytic materials Optical properties of semiconductor nanostructure Light loclization and random lasing
