Department of Engineering Science, Graduate School of Informatics and Engineering,
The University of Electro-Communications


Our research includes the development of biodevices (optical sensor with the visual function、optical memories) applying photosynthetic protein that resembles visual pigments. We also apply the protein to quantum optics. AAnother research interest is to analyze the structure of cell membrane of a living bacterium using nonlinear spectroscopy technique.
We perform joint research projects with: Advancet ICT Research Institute, National Institute of Information and Communications Technology; Near-field NanoPhotonics Research Team, Advanced Science Institute, RIKEN; and Departmet of Applied Physics, Osaka University.

A joint team from Tanaka Lab (M department) and Okada Lab (S department) won Special Award at the 31'st All Japan Micromouse Contest.
The team took part in All Japan Micromouse Contest (hosted by New Tecnology Foundation, Public Interest Incorporated Foundations, co-sponsored by Ministry of Education, Culture, Sports, Science and Technology and Ministry of Economy, Trade and Industry) bringing a first-in-the-world mouse (robot) with bacteriorhodopsin vision sensor. The team's active deployment of cutting-edge technology has been highly credited.
