The lab freely controls light using artificial optical materials that do not exist in nature.
AboutAbout the lab
Innovation in light control with metamaterials and its implementation in society
The Kanamori Lab studies technologies that manipulate light using artificial optical materials not found in nature (metamaterials).
Using structures smaller than the wavelength of light, made by microfabrication, the lab aims for light control that has not been possible before.
The lab also combines biomimetic optics, which imitates the structures and functions of living organisms, with optical MEMS, which moves light using tiny machines.
The lab aims to realize innovative light-control devices and sensor devices and to put them to practical use in society.
Key terms
- Metamaterial
- An artificial material made by arranging structures smaller than the wavelength of light. It can produce optical properties not found in natural substances
- Microfabrication
- A processing technology that creates very small structures on the surface of a material. It is used to fabricate metamaterials
- Optical MEMS
- A technology that uses tiny mechanical mechanisms (MEMS) to move elements and change the properties of light

ResearchResearch themes
The lab develops technologies that freely control light by combining metamaterials, biomimetic nano-optics, and micromachines. Its work covers everything from fabrication technologies for materials and devices to applications in communications and sensing.
*Illustrative imageBiomimetic Nano-Optical Devices
The lab fabricates nanogratings that imitate the structural color of peacock feathers and the antireflective structure of moth eyes. It has developed color filters capable of a wide range of colors and surfaces that suppress reflection.
*Illustrative imageMetamaterials That Control Electromagnetic Waves
Metamaterials are artificial optical materials whose response to electromagnetic waves is determined by their structure. This lab has developed metamaterials that exhibit EIT-like (electromagnetically induced transparency-like) behavior and Fano resonance, absorbers, sensors integrated with photoelectric devices, and mechanically reconfigurable tunable metamaterials.
*Illustrative imageMoving Light with Micromachines
The lab has developed wavelength-selective filters and variable-reflectance filters by precisely controlling the position of photonic crystals with microactuators. It has also succeeded in changing the transmittance of terahertz (THz) waves.
*Illustrative imageNanofabrication of Silicon Surfaces
The lab has developed a technique to smooth silicon surfaces roughened by etching, using the property that surface atoms move in high-temperature hydrogen. It aims to realize ultra-low-loss optical devices and silicon micromechanical components with excellent mechanical strength.
