Concept



System design utilizing light and natural systems

Our goal is to consider the logical structure of the natural world, including light, from the viewpoints of system informatics, appropriate mathematical theory of physical systems and system architecture, and to develop applied technology by means of optoelectronic devices, laser chaos, nano optics, etc. Research is carried on regarding innovative computing such as decision making algorithms and metrics as well as the creation of new functionalities such as physics-based security in simultaneous configurations.

For students: This laboratory is established since April 2019, and is actively engaged in research, including the CREST project. We hope that you will be able to take part in our graduate school (master's course and doctoral course). We are keenly interested in creating new and distinctive research based on our own ideas, not limited to the themes introduced on this website. Let's open up new research areas!

RESEARCH



1) AI Photonics - Decision Making by Photons-

This project physically resolves decision making problem, which is one of the most important elements in information and communications technology (ICT) including artificial intelligence (AI), by utilizing the unique physical nature of photons. Specifically, diffraction-limit-free nano-scale photonic decision making is investigated by utilizing photochromic materials and near-field photons. Furthermore, ultrafast decision making is developed whereby the ultrahigh-bandwidth nature of photons and chaotic dynamics of lasers are exploited. Meanwhile, applications such as instantaneous channel assignment in communications and ultrafast arbitration for solution searching are studied to fully benefit from the potential of our photonic decision making technologies. This topic is funded by JST CREST.

2) Architectural Foundamentals for Functional Systems

The extensive progress of ICT and AI imposes further demands to optics and phtonics while the emergence of new device technologies require novel design of system architectures and data processing technologies. We will explore innovative architectures for arbitration-free information network by precision synchronization technologies, physical securities by nanoscale complex patterns, etc.

3) Natural Computing / Natural Transformation Design

Toward developing computing using natural processes, theoretical fundamentals are important, which is also the key concept of our department highlighting the importance of intertwining physical world and information world. For such purposes, we will explore the concept and the design fundamentals, what we call "Natural Transformation Design" by utilizing modern mathematics including category theory as well as model theories based on empirical findings.
