MISSION

Photonics × Computing: System design utilizing optical physics

The intersection of optics/photonics and information science has a long history and has produced foundational technologies for various fields, including medicine, astronomy, and material science. We—the Information Photonics Laboratory—are working to accelerate this trend further by exploring new optical and computing systems in the interdisciplinary field of optics and information science. We especially aim for minimal and sophisticated system designs that are deeply rooted in the essence of both fields. Our research progresses on two fronts: computational imaging, which seeks to innovate optics through the application of information science, and AI photonics, which aims to revolutionize information science through the use of optics. Through these research efforts, we also aim to cultivate individuals proficient in both natural sciences and information science, who will contribute to society in the future.

For students: We are always open to inquiries and lab visits. Light has excellent advantages as a medium for information transmission and processing, such as high speed, parallelism, and low loss. If you are interested in conceptual research that utilizes light with such unique characteristics to bridge the physical and information worlds, please feel free to contact us.
