The lab develops new measurement and spectroscopy technologies using optical frequency combs.

The Asahara Lab researches the development of new measurement and spectroscopy technologies that use optical frequency combs as a light source. In collaboration with the Minoshima Lab and the Kato Lab (Department of Engineering Science), it holds experiments, lab meetings, and various events jointly as the Minoshima-Asahara-Kato group. In addition to research on dual-comb spectroscopy, the lab works on spectroscopy techniques extended into the spatial dimension, targeting metamaterials and optical vortices. The lab proposes and demonstrates new spectroscopy techniques that make full use of optical frequency combs.

The lab creates measurement and information processing systems that use light.

The Watanabe Lab researches and develops new measurement systems and information processing systems that center on optical technology and combine image processing and information technology. The lab is developing a system that measures the phase information of biological cell samples in a non-contact, non-invasive way, with extremely high precision and speed. It is also working on the miniaturization of an ultrafast optical server for video retrieval. The lab has two research groups: the phase group and the correlation group.

The lab pioneers new methods and new materials for next-generation lasers.

The Shirakawa Lab conducts fundamental research and development of lasers. The lab pioneers new methods, new functions, and new materials for next-generation lasers, working toward higher power, shorter pulses, and higher functionality. The lab's three key research topics are fiber lasers, ceramic lasers, and phase-locked lasers. To join this lab, undergraduates enter the Optical Engineering Program in Category III, and graduate students enter the Department of Engineering Science.

The lab explores precise measurement and control by freely manipulating optical frequency combs.

The Minoshima Lab studies the “optical synthesizer,” which uses optical frequency combs to manipulate light freely. An optical frequency comb is called a “ruler of light”: ultra-precise light whose components line up like the teeth of a comb. The optical synthesizer is a technology that uses the properties of optical frequency combs in time, space, and frequency (color) to play light as if performing music. The ERATO project of the Japan Science and Technology Agency, led by Prof. Minoshima, was carried out in collaboration with the National Institute of Advanced Industrial Science and Technology, several universities, and private companies.

The lab investigates catalyst surfaces using quantum beams.

The Miwa Lab studies the surfaces of catalysts related to fuel cells and hydrogen. The lab carries out operando measurements, using synchrotron radiation X-rays to examine the platinum catalysts of fuel cells while they are generating power. The lab also analyzes catalysts using muons.

The lab observes the movement of bacteria with optical microscopes.

The Nakane Lab studies how microorganisms such as bacteria move. By developing and refining optical microscopy techniques, the lab observes the movement and shape of a single bacterial cell or a single unit of its motility machinery at the micro- and nanoscale. The lab is equipped with instruments for culturing microorganisms, and which bacteria to study is decided in consultation with each student's interests. People who are not familiar with microorganisms or optical microscopy are welcome, and lab visits are accepted at any time.

The lab explores how the circadian clock and odors work in the brain.

The Nakamura Lab studies the circadian clock and odors in the brain. Focusing mainly on brain function and sensory organ function in mammals and insects, the lab uses a variety of methods, including genetic engineering, cell biology, and behavioral science. Currently, the lab mainly studies the circadian clock, using tools such as genetically modified mice that glow in a 24-hour cycle. The lab believes that developing ways to regulate the function of the circadian clock is important for disease prevention, and is particularly interested in regulation by odors.

An organic chemistry lab that takes bioluminescent organisms such as fireflies as its starting point.

The Kitada Lab works with the Hirano and Maki labs to develop organic chemistry research that takes bioluminescent organisms as its starting point. The labs of Professor Hirano (organic photochemistry and physical organic chemistry) and Professor Maki (synthetic organic chemistry and organic electron transfer) are working to open up a new field of chemistry that uses bioluminescent organisms as its molecular foundation. In the Maki Lab, which Associate Professor Kitada has joined, researchers work from the standpoint of organic synthesis on synthesizing optical imaging materials and drugs for leukemia. The lab's website goes by the name 'Hirano & Maki & Kitada Lab' and presents it together with the Hirano Lab and the Maki Lab.
