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

Photonic nanostructures and topological wave engineering

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. Our research focuses on the control of light and light-matter interactions by using photonic nanostructures including photonic crystals, especially, aiming at the development of novel light-emitting devices and quantum optical devices. We are also interested in the generation of unconventional optical beams, such as optical vortexes and Poincare beams, utilizing photonic nanostructures and in their applications. Moreover, we are exploring topological wave engineering aiming at realizing novel control of light, sound, and elastic waves using the concept of topology. We expect the unique features will lead breakthroughs of the device technologies in various fields.

Interactive electronic devices by soft nanomaterials

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 that are 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.
