About the Institute for Photon Science and Technology

The invention of the laser has catalyzed remarkable advances in optical science. In particular, recent progress in laser light source technologies has dramatically extended the accessible wavelength range of coherent light (light with well-aligned wave phases), now spanning from the terahertz region (wavelength ~0.3 mm) to soft X-rays (wavelength ~2 nm). These developments are not only driving cutting-edge research across all fields of fundamental science but also giving rise to essential technologies that underpin modern society.

The Institue for Photon Science and Techology, affiliated with the Graduate School of Science, was established in October 2013 with the aim of creating a new interdisciplinary scientific domain through advanced optical science. By integrating leading research efforts within the university and fostering collaborations with institutions both in Japan and abroad, the Institute seeks to establish the University of Tokyo as a global hub for photon science. In parallel, it actively promotes partnerships with industry to translate the outcomes of fundamental research into technologies that benefit society. Through these efforts, the institute demonstrates that the pursuit of fundamental scientific truth can contribute to solving societal challenges and catalyze transformative innovation—redefining the role of basic science in the modern world.
