Research Overview

I am investigating fluorescence, wavelength conversion and various other optical properties of crystals containing rare-earth ions, clarifying their characteristics as optical crystals, and pursuing possibilities for opening up new wavebands for optical communication, and applications in wideband optical amplifiers and wavelength-tunable light sources.
Another aim is to develop new spectrometry techniques by elucidating fundamental phenomena: light scattering in photonic crystal nanostructures, non-linear light absorption processes in multilevel atomic systems, and coherent transients such as quantum beats, etc.
I am investigating electro-optical characteristics, including transient response, of elements built with organic semiconductors (e.g., electroluminescence elements, sensors and transistors) based on the optical properties of thin-film materials made from organic semiconductors. In this way, I am pursuing practical development of organic EL color displays, and possibilities such as new sensors and systems for photoelectric conversion.
