The three research themes, fiber optics, upconversion, and biophotonics seem to be unconnected, but they can be actually connected. The author studied glass science in a glass laboratory when he was a student, and is currently conducting research on biophotonics using near-infrared light. This paper introduces the development of applications in different fields connected by basic science, starting from glass science and goaling to biophotonics.
