The Ultra-Broadband Communication Infrastructure Lab conducts research to pioneer and put into practical use technologies for millimeter waves and terahertz waves (sub-millimeter waves), an electromagnetic wave region whose technology is still under development. The lab creates new electronic devices and circuit systems that operate in this region, and carries out research and development on applying them to information and communication systems and measurement systems. The lab consists of the Ultra-Broadband Device Physics research field led by Professor Sato and the Ultra-Broadband Quantum Electronics research field led by Associate Professor Lin. It belongs to the Information and Communication Infrastructure Division of the Research Institute of Electrical Communication.

The Environmentally Harmonious Secure Information Systems Lab researches next-generation information security systems, aiming to build an information and communication infrastructure that anyone can use with confidence. The lab considers that in next-generation information and communication infrastructure such as the Internet of Things, security cannot always be maintained by simply extending existing technologies. The lab develops technologies that ensure safety and reliability not only for networks and software but starting from the level of device hardware such as sensor devices. The lab is also working on putting its research results into use in society and on standardization.

The Novel-Concept VLSI Systems Lab (the Hanyu-Natsui-Onizawa Lab) researches design technologies for very-large-scale integrated circuits (VLSI) based on new ideas. Performance improvements in integrated circuits have been driven mainly by advances in microfabrication, but this approach alone is expected to reach its limit. The lab therefore aims to overcome that limit not only with conventional silicon CMOS circuits but also with circuit design methods and system configurations that make use of the characteristics of new materials and devices. Another goal is to realize highly functional, multifunctional VLSI that imitates the intelligent activity of the human brain.

The Saito-Ogawa Lab belongs to the Ultrafine Electronics Division in the Department of Electronic Engineering, Graduate School of Engineering, Tohoku University. The research page lists next-generation hard disks, Fe-based spin nanoclusters, magnetic powder for next-generation ICT, and light–spin properties as research themes. The lab's website posts research videos, mainly as a lab introduction for third-year undergraduates.

The Plasma Science and Technology Lab clarifies the properties of plasma in contact with liquids and studies its applications. At atmospheric pressure, the lab uses its own techniques to visualize and study fast phenomena occurring at the interface between plasma and liquid. Using plasma generated from air and water, the lab produces reactive species used to inactivate bacteria and viruses, and works on developing new sterilization technologies. Building on electrical and information engineering, the lab conducts joint research with researchers in agriculture, medicine, chemistry, and materials, as well as with private companies.
Toshiaki Kato, Professor

The Kato-Okada Lab develops techniques to synthesize atomic-layer materials such as carbon nanotubes and graphene with high quality and give them functions. The lab studies the entire process consistently, from material synthesis to device design, fabrication, and functional evaluation. The nanomaterials the lab works with are extremely small, on the scale of one-billionth of a meter, and their functions change greatly with a difference of a single atom in structure. The lab also uses methods that combine its original nanomaterial synthesis technology with modern AI technology.

The Photonic Device Engineering Lab studies a variety of photonic devices based on photonic crystals, optical nanostructures that can control light freely. Light has physical quantities such as color (wavelength), intensity (amplitude), phase, and polarization. The lab specializes in spatially designing the physical quantities of laser beams. Its work includes research on controlling the polarization state of beams emitted from photonic-crystal lasers, and research on strained photonic crystals that can bend light.
Eiji Higurashi, Professor

The Higurashi-Takeuchi Lab studies heterogeneous integration technology, which integrates dissimilar materials and dissimilar functions, and low-temperature bonding technology. In the semiconductor field, multifunctionality and the fusion of different functions are advancing alongside miniaturization, and the integration of dissimilar materials is attracting attention as a key to the continued growth of the semiconductor industry. The lab aims to contribute to creating electronic and optical devices, sensors, actuators, and energy devices that are compact, high-performance, and energy-efficient. It also aims to contribute to advancing the electronic equipment systems that will support the future IoT society.
Tatsuo Yoshinobu, Professor

Aiming to fuse semiconductor electronics with biological functions, the Yoshinobu Lab studies chemical imaging sensors that turn the distribution of ion concentrations into images. An ordinary image sensor is a sensor that "sees light," whereas a chemical imaging sensor is a sensor that "sees ions." In addition to images of pH (hydrogen ion concentration), the sensors can measure the distribution of various ions, and applications include analysis of electrochemical systems, detection of live bacteria, observation of cells, and visualization of the inside of microfluidic devices. On the lab's website, the lab is introduced under the name "Yoshinobu-Miyamoto Lab."

The Solid-State Electronics Lab uses next-generation device materials such as graphene, nitride semiconductors, and diamond to conduct integrated research from materials to devices. Electronics, long supported by silicon technology, now faces the limits of silicon's physical properties and the barriers of ultrafine fabrication technology and cost. Developing high-performance devices from materials other than silicon is therefore regarded as a major challenge for society.
