Toward innovative device/system technologies enabled with advanced photonic nanostructures and nano-sized electronic materials: from physics, materials to devices and systems

Nanophotonics and topological wave engineering (Iwamoto Laboratory)

Photonic crystals are artificial optical materials possessing a wavelength-scale periodic structure in refractive index. Novel optical functionalities and unique optical phenomena can be realized using photonic crystals. We are investigating the physics of controlling light and light-matter interactions using photonic crystals and other photonic nanostructures, as well as their application to optical and quantum devices. We are also ambitiously exploring nanophotonics technologies based on wide bandgap materials such as diamond and gallium oxide. Another important research subject in our group is topological wave engineering. We aim to realize novel control of light, sound, and elastic waves using the concept of topology, and innovative applications based on them.

Nano-sized electronic materials, such as metal nanowires, conjugated polymers, and carbon nanotubes, have high flexibility that traditional electronic materials like silicon do not have. These soft nano-electronic materials enable electronic devices highly compatible with soft human tissue, such as computer interfaces that integrate with skin and healthcare sensors that can accurately measure biological signals over a long time. We develop novel soft materials, evaluate devices, and explore novel applications, aiming to create interactive electronics that seamlessly integrate into our daily lives.

One of the secrets to enjoying research is to maintain a clear distinction between work and rest. No matter how busy I am, I make sure to refresh myself almost every weekend at the sauna. At first, I think about work, but eventually, I forget about it. However, it's during such times that research ideas often come to mind. The lab members who hear about them might always feel troubled because most of the time, it's a 'no, it didn't work out.' But some of these ideas have successfully developed. (Iwamoto)

I believe that to conduct interesting and cutting-edge research, it is crucial to maximize the variety and number of people involved in the research. To achieve this, I think it is important to disseminate information through social media (please follow me on X and Instagram: @naoji_tokyo) and outreach activities, and to communicate in a way that is clear and engaging. RCAST, where diverse researchers gather, is the perfect environment for this. (Matsuhisa)
