Kei Sakaguchi, Professor
1 student voices
The Sakaguchi Lab (formerly the Araki-Sakaguchi Lab) studies wireless technologies, building on wireless communication systems. Its work is wide-ranging, from theoretical analysis to hardware implementation, building measurement systems, and field trials. Together with companies in Japan and abroad, it develops new wireless applications and takes part in setting standards for next-generation wireless systems. The lab is run jointly with the Tan Lab.
Atsushi Shirane, Associate Professor
1 student voices
The Shirane Lab studies integrated circuits for wireless communication and wireless power transfer. To extend the reach of wireless communication into space, the lab builds radios and wireless ICs to be mounted on satellites. Using wireless power transfer, which sends power by radio waves, the lab also aims to realize radios that need no power source. As the power used for communication keeps growing, the lab works on research into wireless devices that are gentle on the global environment.
Keigo Arai, Associate Professor
1 student voices
The Arai Lab studies quantum sensing using "NV centers" in diamond. By combining quantum sensing with computational informatics, the lab aims for innovation that it calls "quantum transformation." The lab works to develop quantum sensors that precisely measure nanoscale magnetic fields and temperature into measurement tools that can be used outside the laboratory. Students can experience the whole research process, from theory and numerical simulation to building equipment, experiments, data analysis, and presentations.
Nobuhiko Nishiyama, Professor
1 student voices
Nishiyama Lab studies optoelectronics, in particular photonic-electronic integrated circuits centered on semiconductor lasers. It aims to realize low-power, efficient, high-capacity optical communication and optical sensors. The lab works broadly, from circuit design to materials, crystal growth, device fabrication, and evaluation, using state-of-the-art facilities. A distinctive strength is the ability to make optical devices such as semiconductor lasers starting from crystal growth, and the lab conducts joint research with many companies.
Takashi Tokuda, Professor
1 student voices
The Tokuda Lab researches new device technologies that combine semiconductor materials, electronic circuits, and device processes. In particular, it works on biosensors including image sensors, ultra-small medical devices that can be implanted in the body, and IoT/IoE. One pillar of its research is technology for running electronic devices of a few millimeters or less on power delivered by light. The lab belongs to the Laboratory for Future Interdisciplinary Research of Science and Technology, Institute of Integrated Research, and its students are assigned from the Department of Electrical and Electronic Engineering, School of Engineering.
Tetsuo Kodera, Professor
1 student voices
The Kodera Lab conducts research to realize quantum computers using semiconductors such as silicon. Electrons and other particles are confined in fine semiconductor structures called quantum dots, and their spins are used as qubits. A strength of this approach is that it can draw on the semiconductor manufacturing technology used in PCs and smartphones. To operate quantum computer devices, the lab conducts experiments using refrigerators that can cool to near absolute zero and low-noise control and measurement equipment.
Kentaro Nakamura, Professor
1 student voices
The Nakamura Lab studies sensors and actuators that use ultrasound and light waves. The lab aims to use ultrasound and light to realize sensors and actuators that are difficult to build with other methods. Its work includes motors driven by ultrasonic vibration and sensors that use optical fibers to measure stretching and temperature. Each student takes charge of one theme on their own and is involved in everything from design to prototyping, analysis, and evaluation.
Hiroshi Akatsuka, Associate Professor
1 student voices
The Akatsuka Lab researches plasma science and engineering, centered on plasma spectroscopy. The lab builds numerical models of how atoms and molecules emit light inside plasma, and combines them with simple spectroscopic measurements to develop methods for determining the state of a plasma. It also does fundamental research on flows of weakly ionized plasma that expand at supersonic speed. This is a field that draws on knowledge of physics, chemistry, mechanical engineering, and electrical engineering, and people from a wide range of departments are active in it.
Hiroyuki Ito, Professor
1 student voices
The Ito Lab studies analog integrated circuit and integrated MEMS technologies, and their applications. Aiming at electronics for sustainable medicine, healthcare, and food production, the lab develops technologies that measure people, animals, and the environment by focusing on "vibration." Centered on silicon integrated circuit technology, the lab pursues higher sensitivity in sensors and lower power consumption in wireless sensors. Alongside its research, the lab also works in parallel on efforts to put the technologies it develops to use in society.
Pham Nam Hai, Professor
1 student voices
The Pham Lab studies materials and devices for spin-based semiconductors, which combine the features of semiconductors and magnetic materials. Semiconductors operate quickly, while magnetic materials can store data without consuming power, so combining the two is expected to yield devices with extremely high energy efficiency. The lab works on "spin device engineering," which spans materials engineering, solid-state physics, and device engineering. The lab is conducting research on SOT-MRAM, a low-power next-generation memory that uses topological insulators, jointly with companies.
